Dr. Asis Kumar Chaudhuri a theoretical physicist Variable Energy Cyclotron Centre Kolkata India



Dr Asis Kumar Chaudhuri a Physicist

About Dr. Asis Kumar Chaudhuri 


Dr. Asis Kumar Chaudhuri is a theoretical physicist at the Variable Energy Cyclotron Centre (VECC), Kolkata; a premier research institute in India. He was Outstanding Scientist at VECC and Senior professor at HBNI. Born on 15th December 1956, in Cooch Behar (erstwhile a princely state and presently a district of West Bengal), he had his schooling at   Jenkins School, one of the oldest educational institute (established in 1861) of India. He graduated from the Acharya Brajendra Nath Seal College (formerly known as Victoria College) and obtained Masters from University of North Bengal. He did his Ph.D. from the University of Calcutta under the supervision of Prof. Bikash Sinha, a prominent name in Indian Science.

In 1981, following initial training at the prestigious Training School of Bhabha Atomic Research Centre, Mumbai, Dr. Chaudhuri joined Variable Energy Cyclotron Centre, Kolkata. He started his research career in low energy nuclear physics. In his Ph.D. thesis, “Nuclear   medium   effects   in  the  single  particle description  of  nucleus-nucleus  interaction  potential  in  the continuum,” he examined the role of nuclear medium on optical model potential and showed that the nucleus-nucleus interaction potential, consistent with experimental data, can be obtained from the basic nucleon-nucleon interaction with medium effects properly incorporated. In later years, he was interested in high energy nuclear physics, in particular in relativistic heavy ion collisions and Quark-Gluon Plasma. His pioneering work on the application of dissipative hydrodynamics in relativistic heavy ion collisions, in particular in characterizing transport properties of QGP is recognized world over. One of his important achievements is the development of a computer code "`AZHYDRO-KOLKATA"' for solving dissipative hydrodynamics equations. The code was used to determine precisely, the QGP viscosity over entropy ratio, with statistical and systematic uncertainties.

Additionally, Dr. Chaudhuri has published two well-acclaimed books. In 2014, The Institute of Physics, London, published his  advanced textbook, "A short course on Relativistic Heavy Ion Collisions." The book was well received by students and researchers of high energy nuclear physics.  In 2016, World Scientific, Singapore  published his popular science book, "Cooking Cosmos: Unraveling the mysteries of the Universe." The book discusses the evolution of scientific thoughts about our cosmos, starting from Aristotle's Earth-centered Universe to the Big Bang model of Universe to the presently accepted Expanding Universe.

The evil of religious fundamentalism cannot be countered only by economic development or political goodwill. True scientific spirit needs to be inculcated among the world's populace. And this book tries to do it, inculcate true scientific spirit.

The famous picture of the fifth Solvay Conference 1927, shown below may have seen every physicist around the globe, Dr. Asis Chaudhuri briefly explained it in his post. All the 29 great physicists details are included here in this post. 

Dr. Chaudhuri believes that science is the key to human freedom; freedom from religious bondage, freedom from superstition, freedom from poverty, freedom from hunger. In recent years, apart from his research work, through various writings, he is trying to popularise science. His popular writings can be found on the WordPress blog.  
Dr. Chaudhuri also made important contributions to the understanding Charmonium (bound state of a charm-anticharm pair) production in high energy nuclear collisions. He has a healthy interest in other areas of physics, e.g. chaos, early universe, physics beyond standard model etc. and occasionally contributed scientifically in those areas. He has published more than 100 research articles

Late Prof. Walter Greiner; Professor Emeritus of Physics, Institute for Theoretical Physics Founding Director, Frankfurt Institute for Advanced Studies Johann Wolfgang Goethe-Universität, Frankfurt am Main

Prof. Walter Greiner scientist
(Source: fias.uni-frankfurt.de)
Prof. Walter Greiner a theoretical physicist was born on Oct 29, 1935 in Neuenbau, Sonnenberg, died Oct 15, 2016 at the age of 80 yrs in Germany. His research interests lie in atomic physics, heavy ion physics, nuclear physics, elementary particle physics (particularly in quantum electrodynamics and quantum chromodynamics). He is known for his series of books in theoretical physics[1]. Walter Greiner's books are good and instructive and cover most of theoretical physics, with a focus on quantum physics and its various parts (non-relativistic quantum mechanics, symmetries and group theory in QM, quantum field theory, QED, QCD, etc). There are helpful mathematical results and derivations as well as many worked out exercises in each book. Sometimes the translation from German is not very accurate, and sometimes there are typos, but overall this book series is useful and informative [3]. Prof Greiner was also associated with Indian Physicists (Prof. Raj K Gupta, PU Chandigarh and Prof. S K Patra, IOP Bhubaneswar) and contributed significantly in Superheavy Nuclei research.  

Walter Greiner's remarkably productive life of a brilliant scientist devoted to theoretical nuclear science during the last four decades is an example of an unparalleled success story. Many new topics in Nuclear Structure, Nuclear Reactions, Atomic Physics, and Particle Physics were initiated by him and he has been a leading scientist for many years, guiding the experiments, and other theoretical developments. One can mention some of them below.


Nuclear polarization in muonic atoms. Rotation-vibration model. Dynamic collective model of giant resonances. Eigenchannel theory of the S-matrix nuclear reactions. Superheavy nuclei, structure, stability against fission, alpha decay and electron capture. Electronic structure of superheavies. Theory of nuclear molecules, coupled channel formulation of nuclear molecular reactions. The two center shell model which is fundamental for all fission and fusion processes. Generalized collective model (Gneuss-Greiner model). Fragmentation theory. Prediction of the cold valley for fusion of superheavy elements.

Calculations of PES exhibiting the cold valleys for fusion, cold fission bimodal fission, cluster radioactivities, and alpha decay. Quantum Electro Dynamics of strong fields, spontaneous pair creation, superheavy quasimolecules. Supercritical fields in other areas like gravitation (Hawking radiation) and strong color fields. The prediction of nuclear shock waves as a key mechanism for compressing and heating nuclear matter. This work initiated high energy nuclear physics: search for the nuclear equation of state and possible phase transitions. Antimatter clusters emitted from a quark-gluon plasma. Meson field theory for hot and dense nuclear matter, phase transition, chiral restoration. Meson field theory applied to nuclei and exotic objects, e.g. multi-Lambda-nuclei.
Relativistic fluid dynamics for high energy heavy ion collisions. Antimatter production in thermal meson field theory. Quantum molecular dynamics applied to nuclear collisions. Relativistic quantum molecular dynamics. Antiflow of pions and antimatter. Quark-gluon plasma as a cluster plasma. Extension of the periodic system into the new directions of strangeness and antimatter. Structure of the baryonic and mesonic vacuum of high densities and temperature. A new mechanism for cold compression of an elementary matter by implantation of high energy antiprotons in nuclei.




No one has made so many significant contributions in so many different areas of nuclear, atomic and particle physics. His seminal ideas concerning superheavy nuclei have head enormous impact on the development and progress of heavy ion physics in Germany (GSI) and worldwide. He has set new directions that will carry us many years into the next decades. He extended his influence and impacts through a remarkable career in training young scientists in their PhD research. They now fill important positions in Universities and Industries around the world. In scientific cooperations, he stimulated, challenged, and enhanced the research of his partners in many ways. Professor Greiner co-founded a new Institute of Research: the Frankfurt Institute for Advanced Studies. [4]

ABHAS MITRA- Head (Retd.), Theoretical Astrophysics Section, Astrophysical Sciences Division, BARC, Mumbai, INDIA



Prof. Abhas Mitra


About Prof. Abhas Mitra 



Prof. Abhas Mitra (born on June 03, 1955 at Belur, West Bengal), is Head, Theoretical Astrophysics Section, Astrophysical Sciences Division (APSD), Bhabha Atomic Research Centre (BARC), Mumbai -400094, since 2005; Technically, Scientific Officer (H+). Ph.D. guide (Physics) for Mumbai University & Homi Bhabha National Institute (HBNI) where he is an Adjunct Professor. he has completed their basic Educational Qualifications: (i) M.Sc. (Physics), 1st Class, University of Kolkata (1977). But results came in 1979 because of ultra-left political turmoil. (ii) BARC Training School, 23rd Batch (3rd in Physics stream): Aug 1979 – July 1980. This was more than a M. Phil degree. (iii) Ph.D. Thesis entitled ``A New Theory of Ultra High Energy Gamma Ray Production In Cygnus X-3’’ was ready for submission to Kashmir University in 1990. But because of militant uprising, this could not be done. Later an updated thesis was submitted in Mumbai University, & degree obtained in 1994. This thesis contained all single authored papers in leading international journals and hence equivalent to a D.Sc. degree (guide was only an official formality).
He is one of the rare astrophysicists in the world whose research has spanned such a wide range:
  •  Gamma Ray Astronomy, X-ray Binaries & Millisecond pulsars, Cosmic Gamma Ray Bursts, Diffusive Shock Acceleration, General Relativity, Gravitational Collapse, Various aspects of Cosmology, Classical Mechanics. He happens to be only Relativistic Astrophysicist & Cosmologist in the 67 year history of BARC.
  • Initiated serious research in Theoretical Astrophysics singlehandedly not only in APSD/BARC but also in the state of J&K of India by braving immense difficulties.
  • First to show that photo-meson process could be the leading source of high energy cosmic
  • gamma-rays in some X-ray binaries. His research on Cygnus X-3 got cited in Nature News & Views (P.S. Conti, Nature 355, 680, 1992).Another paper on Cygnus X-3, got discussed in the prestigious international magazine Sky & Telescope in 1998: http://connection.ebscohost.com/c/articles/906966/questioning-cygnus-x-3s-black-hole  In India, he pioneered the theoretical research on Cosmic Gamma Ray Bursts. He was the first ever speaker (amongst only 12 worldwide) from India in famous (1995), 3rd Huntsville Gamma Ray Burst Conf: http://gammaray.nsstc.nasa.gov/events/3hgrbs/abstracts/models.html
  •   One of the very few BARC scientists who has delivered prestigious ``Wednesday Colloquium’’ in Tata Institute of Fundamental Research, Mumbai (On Gamma Ray Burst research).


Prof. Abhas Mitra selected for European Commission – DST (India) Post Doc position to work with Prof. (Sir) Martin Rees (later Astronomer Royale), Cambridge University, in 1992. But this did not materialize in the absence of a formal Ph.D. degree. His career in BARC did not offer any scope for formal teaching. However, he is competent to teach all areas of physics (except biological physics) at any level.

Prof. Abhas Mitra is one of the rare active Indian scientists who write blogs on own research in astrophysics & cosmology from various platforms:
·         https://eternalblogs.wordpress.com/
He is the administrator of 3 Facebook pages promoting astrophysics & cosmology:
·         https://www.facebook.com/groups/180463648732274/ (Cosmology Without Prejudice)
·         https://www.facebook.com/EternallyCollapsingObject
·         https://www.facebook.com/MECONOTBH
In addition, he regularly participates in various astrophysics/cosmology debates in Facebook groups like ``Astronomy’’, ``Cosmology’’, ``Astrophysics & Physics’’.

He has been invited as Key Speakers or Guests by many organizations in past 10 years. On several occasions, he has answered innumerable queries on various topics of physics & astrophysics from gathering of around ten thousand school students. In 2013-14, he was invited by Guwahati University, M S University, Baroda and IIT Kharagpur to address students on his research:

https://www.facebook.com/events/317525788425216/ (Prof. Somnath Sengupta Memorial Lecture)


·       Presently NASA operates the space borne Gamma Ray Telescope ``Fermi’’ whose original name was GLAST. The science brochure of GLAST cited only one paper of Indian origin which is  by R. Kaul & A. Mitra:

As a Section Head, he gave full academic freedom to younger colleagues to pursue their independent research problems, and did away with the frequent practice of having the name of the ``boss’’ as one of the coauthors (otherwise his list of publication could have been much longer)! He has visited labs/universities/conferences in USA, UK, Russia, China, Hong Kong, France, Germany: where he gave lectures, plenary/invited talks on own research. He is involved in the simulation & development of new data analysis program (Random Forest Method) for the MACE project (one of the largest Gamma Ray Telescope of the world) at Hanle, Ladakh (in collaboration with TIFR & Indian Institute Astronomy).


He is the first physicist to not only show/claim that the so-called ``Black Holes’’ (a crucial concept in Astrophysics & Physics for 100 years) cannot be true black holes, but also suggested the most likely nature of such objects. This research is based on series of peer reviewed and uncontested publications in journals such as Found. Phys. Lett., Pramana, Advan. Sp. Sc.,  Astrophys. Sp. Sc., New Astronomy, Int. J. Mod. Phys. D., J. Math. Phys, IJAA, JMP, Phys. Rev. D., Mon. Not. Roy. Astron. Soc., Mon. Not. Roy. Astron. Soc. Lett.

His research has shown that though the Black Hole solution is formally correct, the pertinent Integration Constant is zero implying true BHs (point particles) have gravitational mass M=0, and therefore the so-called BHs having M>0 cannot be true BHs. On the other hand, his research has shown that, as massive objects keep on contracting, at some stage, the outward pressure of trapped radiation must be able to counteract the inward pull of gravity to result in quasi-static ultra-compact hot objects which nonetheless keep on contracting indefinitely (Eternally Collapsing Objects: ECO). Astrophysical ECOs are likely to be ultra-magnetized too (MECOs)  And now there are many evidences that many BH candidates possess strong magnetic field which cannot be due to effect of surrounding accretion disks. For instance see: Surprisingly Strong Magnetic Fields Challenge Black Holes’ Pull or ``Dynamically important magnetic fields near accreting supermassive black holes’’ (Nature, 510, 126, 2014). Accordingly, his BH research has been discussed widely both at national & international levels. Please see section 4 in details.




1. SENIOR VISITING POSITIONS:

Worked as a visiting professor in Max Planck Institute for Nuclear Physics, Heidelberg, Germany in 2006. Got qualified as an USA National Research Council SENIOR ASSOCIATE, High Energy Astrophysics Group, Goddard Space Flight Centre, NASA in 2004. But Indian scientists were informally banned in US Govt. Labs following Pokhran II nuclear explosion by India.



2.  PROFESSIONAL HONORS:


·         Distinguished Alumnus of Mumbai University: Only BARC scientist on this list apart from H.J. Bhabha, H. Sethna, R. Ramanna & A. Kakodkar (who all were Directors& Chairmen, DAE): http://www.mu.ac.in/alumni.html

As per ResearchGate: https://www.researchgate.net/profile/Abhas_Mitra,

 Impact Point (IP) of the journal papers is 210. Since most of them are a single author, the IP/Author is ~200, which is high by not only, BARC or Indian standards, but by international standard too. The average IP/Author of other APSD scientists is ~10, the same for BARC scientists/engineers is probably ~3.







4. BLACK HOLE ALTERNATIVE

He is the first physicist to not only show/claim that the so-called ``Black Holes’’ (a crucial concept in Astrophysics & Physics for 100 years) cannot be true black holes, but also suggested the most likely nature of such objects. Details about BH research at national & international levels


Indian Physicist AbhasMitra Claims he Resolved Black Hole Paradox Years before Stephen Hawking (International Business Times, 2014)
No Black Holes After All? (World Science, 2006)

Following his pioneering research, since, 2001, various other researchers too started claiming that ``There cannot be true black holes or gravitational collapse should be singularity free’’, though such researchers would avoid citing the pioneer. Only few examples below:

  Black holes 'do not exist' (Nature News, 2005)
No More Black Holes? (SCIENCE, 2007)



5. RESEARCH IN COSMOLOGY:

For the first time he obtained the ``Curvature Form’’ of the FRW metric used to describe an isotropic & homogeneous universe. Also, for the first time, he derived the FRW metric by actually solving all relevant Einstein equations rather than by relying on geometric arguments.



 DARK ENERGY:

The 2011 Nobel Prize in physics involved the concept of a mysterious cosmic repulsive force called ``Dark Energy’’.  Any many leading cosmologists including (G F R Ellis) have argued that ``Dark Energy’’ might be an artifact of ``back reaction’’ of a real universe which is significantly inhomogeneous. Such an idea has been confirmed by 4 research papers by him which have shown that, the most likely candidate for Dark Energy, namely, the Cosmological Constant of Einstein, is exactly zero.



COSMIC INFLATION:

His 2 papers in General Relativity & Gravitation and New Astronomy have shown that in order that energy density of the FRW universe (including matter & field) is unique, it can expand only in a unique linear fashion. This exact result rules out the hypothesis of ``Cosmic Inflation’’, and accordingly, he insisted that the 2014 BICEP2 claim of confirmation of ``Cosmic Inflation’’ must be incorrect. In 2015, his prediction has been re-confirmed: Cosmic inflation theory of Big Bang bites the space dust (Nature, Feb 02, 2015).





Unknown Inhomogeneous Universe: 

In 2014, his paper in Mon. Not. Roy. Astron. Soc, showed that a linearly expanding Big Bang universe is actually vacuumed and the ``expansion’’ is a mathematical illusion, a coordinate effect. In effect, this means that only pure vacuum can be perfectly homogeneous & isotropic. In other words, the real universe containing galaxies must be inhomogeneous and complex. Indeed, the study of cosmic gamma ray bursts at largest scales (3 Gpc, z=2) indicates that the universe is inhomogeneous and lumpy.
His research on cosmology has been published in IJAA, JMP, Astrophys.Sp.Sc.,New Astron, GRC, GC, Results in Phys., Nature Sc. Rep., IJMPD, JCAP and MNRAS, and has drawn intense media attention:

``Indian physicist questions 'Big Bang' basics’’ (Nature India, 2012)
(Actually, Indian physicist challenges Nobel laureate’s claim of Dark Energy)
``Indian Scientist Contests ``Big Bang’’ Evidences’’ (Business Standard, 2014)

For instance, in this context, internationally famous science communicator and cosmologist Neil deGrasse Tyson (Ph.D. Columbia) wrote ``Steinhardt follows Mitra and points out that there are other twists produced within our own Galaxy’’.
As per Big Bang model, 85% of the matter in the universe comprises unusual (non-baryonic) exotic ``Dark Matter’’. But protracted intense search by (i) Direct Laboratory methods, (ii) Particle Accelerators and (ii) Indirect searches by Gamma Ray Astronomy have failed to detect any WIMP/AXION, and this hypothesis is on the verge of abandonment. This development is in conformity with the idea of Mitra (and many others) that the Big Bang paradigm could be in error (Cosmologists in the Dark, Martinez & Trimble). In his view, galactic DM could just be baryonic matter like ultra-cold molecular hydrogen.
A recent discovery (Science, 2015) that the speed of only strictly plane light waves is constant in a vacuum may have profound implications for Cosmology.


 

6.  BOTTOMLINE: 

Physics problems in the physical Universe involve various complexities like inhomogeneity, heat flow, radiation transfer, the ever-changing equation of state of matter etc. If such complexities would be incorporated, even Newtonian physics, let alone far more complicated General Relativity, would never yield any nice ``Exact Solution’’. This implies that the ``Exact solutions’ of GR, on which the ``Black Hole’’ and ``Big Bang’’ paradigms have been built over past 100 years cannot represent the real throbbing live universe. His research has proved this simple truth by showing that some crucial `exact solutions’/singularities’ are illusory for the real universe, which suggests that the so-called ``black holes’’ are much more lively & interesting objects; and the physical universe is much richer & complex, and of course unknown.
