Professor Walter Greiner a theoretical scientist, was born on Oct 29, 1935, in Neuenbau, Sonnenberg, and 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) [2]. 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].

Collaboration with Indian Scientist:

Professor Greiner was also associated with Indian Scientist (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 the 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.

A scientist with broad vision:

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 a 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 scientist (s) in their Ph.D. 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. Scientist, Professor Greiner co-founded a new Institute of Research: the Frankfurt Institute for Advanced Studies. [4]
