Tara Das

Research Areas:

My research interests have been, and continue to be, focused on the first-principle understanding of electronic structures of atomic, molecular, solid-state and biological systems including the aim to explain their spectroscopic (optical, ultraviolet and infrared), magnetic and hyperfine properties. My research group, especially the Ph.D. students, and post-doctoral physicists, are trained to interact closely with experimentalists, using their theoretical predictions of properties of systems to compare with experimental results and in partnership with experimental groups try to attain a proper understanding of the mechanisms and factors that contribute to a variety of properties including magnetic and hyperfine properties, the latter being obtained by experimentalists by a variety of experimental techniques, ranging from laser techniques for atomic properties to various magnetic resonance techniques, including nuclear magnetic and quadrupole resonance and electron paramagnetic resonance, and associated refinements in these, including a variety of double resonance techniques for solid state (including systems of interest in material) and biological systems.

Exceptional Achievements by Dr. Scheicher after his graduate career

            I will be remarking about Dr. Scheicher`s many publications in a number of current fields besides the ones with my group after he finished his Ph.D. thesis, when I talk about his unusually strong research profile in remarking on the exceptional achievements by some of my past students.

            Additionally, Dr. Scheicher is a member of the Advisory Board for my Book Series. He is the youngest member, but he has been very valuable for in depth discussions about Books to choose for the Series that would be most valuable for current research developments in Materials Science, NanoScience and Biophysics. He has also provided valuable assistance in the choices of authors for Books in various Fields.

2. Dr. Junho Jeong  Dr. Jeong finished his Ph.D. thesis under my supervision in May 2004 in the field of Muonium interactions in Organic ferromagnets and in the study of location of Er3+ in silicon as well as 69Ga and 14N nuclear quadrupole interactions in GaN.

            He is now on the faculty of a leading University in South Korea,University of Uhlsan, (the headquarters for manufacture of Hyundai motor vehicles). He is active in research in Materials Science but I have not been able to be in close contact with him to say much about his current research interests.

            Regarding his Publications based on his Ph.D. thesis work and Conference Presentations about his research work, I will list his papers and presentation in the same way as I have done for the other three of my Ph.D. students based on my own publication and conference presentation lists.

7.  Recent Outstanding Achievements of Past Ph.D. students

1. Professor Bhanu Pratap Das:  Professor in Institute of Astrophysics inBangalore, India: Professor B.P. Das did his Ph.D. thesis with me in early 1980’s. His Ph.D. thesis was based on understanding of many-body effects on properties of heavy atoms using first principles relativistic Hartree-Fock theory combined with many-body perturbation theory. He studied magnetic hyperfine interactions in atomic systems and forbidden optical transitions that result from charge and parity violation effects in particle physics. He had worked on thallium and used the strength of the forbidden transitions to make accurate conclusions about the strength of fundamental interactions leading to charge and parity violation effects.

            He has recently predicted electric dipole moments by relativistic many-body theory (involving a procedure somewhat different than what he used for his Ph.D. thesis work) and compared it with it recent measurements for mercury atom. This work has been published in Phys. Rev. Letters, a very prestigious journal of American Physical Society, the same one where he had published his Ph.D. thesis work on Thallium. The recent experimental work and his theoretical work are receiving much attention in the scientific communities in both atomic physics and fundamental particle physics theory.

2. Professor Ranjit Pati:  Associate Professor in Michigan Technological (Michigan Tech) University. He received his Ph.D. degree under my supervision in 1997, working on electronic structure and hyperfine interactions (especially nuclear quadrupole interactions) in molecules involved in drugs and explosives and also on surface adsorbed atoms in semiconductors.

            He has become one of the leading experts in the theory of molecular electronics, especially the molecule- metal terminals. His work has been published in a number of leading journals including Physical Review Letters. His latest work about nine months back on metal-molecule junctions has received wide attention in news publications of recent breakthroughs in materials research. He has a sizable research group in his field at Michigan Tech and has an NSF Career Award Support for his research for the next five years. He is also a member of my Advisory Board for the Elsevier Book Series that I edit and gives me very valuable advice.

3.  Dr. Ralph H. Scheicher:  Research Scientist in Condensed Matter Theory in Uppsala University, Sweden. I have already described his PhD thesis work and continuing active collaboration with my research group and his own substantial research work since leaving the University at Albany after receiving his Ph.D. thesis degree which extends over many areas of materials science, nanoscience and biophysics. These fields involve interaction between DNA and carbon nanotubes, DNA sequencing using DNA-carbon nanotube interaction, storage of hydrogen (in the field of alternate energy resources) in porous materials and in light-metal hydride systems, metal-insulator transitions and superconducting behavior under pressure in hydrogen-rich materials.

            He is very widely sought after for international collaborations in many countries, including China, Malaysia, South Korea, Brazil and United States. For someone who has received his Ph.D. degree only five years back, the unusually large volume of publications in leading physics journals and interacting so actively with so many leading international groups is truly unusual and a source of great pride for our University and Department.

4. Professor Purusottam Jena:  Distinguished Professor of Physics inVirginia Commonwealth University in Richmond, Virginia. He received his PhD thesis under my supervision from University of California, Riversidein 1970. His work involved study of band structures of metallic systems to understand electronic wave-function dependent properties. He continued on with metallic systems after his Ph.D. work, getting involved in the nature of hydrogen as impurity in metals and also moved on to do pioneering work on structures of metal, and hydrogen atom clusters, a field in which he is a leading authority. He then used his expertise in the two fields to study hydrogen storage in metals and then moved on to lighter systems than metals such as magnesium hydride compounds. He has become a well-known authority on hydrogen storage for use as an alternate energy resource

            In the year 2007-2008 he was appointed as a Jefferson Fellow, a very prestigious position in the US State Department, for providing advice on scientific matters and international scientific interactions. He was the Scientific Advisor for a large International Conference on Alternate Energy Resources organized by the State Department in 2008. He has returned to his Distinguished Professor position at his University but continues to advise the State Department on energy matters and is often designated to attend important International Conferences on Alternate Energy Resources.

            He is also on the Advisory Board for my Book Series, and is Volume Editor for a Book on “Clusters-Bridge across Disciplines” which is expected to be published soon.

            Professor Jena’s recognition as a leading scientist in a number of current fields of research and application interest, and recognition by the Federal Government as a Scientist to seek advice from, is a matter of great pride. He was a post-doctoral scientist in the Physics Department at the University at Albany for the year 1970-71 immediately after completion of his Ph.D. degree in 1970, one year before I joined the Faculty here.
