ABOUT ME - Brief Bio
My specialty is in the area of nanoscience and modern condensed matter physics, exact diagonalization, high temperature superconductivity, quantum computations and magnetism, applications of synchrotron radiations in studies of material characteristics in extreme conditions of interstitial space. I was a Principal Investigator of a number of funding projects in the Institute of Nuclear Physics in Moscow, Institute of Atomic Energy in Yerevan, and was honored in 1991 by a Doctor of Sciences degree. Since 1972 I was working on the problem of high temperature superconductivity in the Lebedev Physics Institute at the Tamm's Department of Theoretical Physics under the supervision of the Nobel Prize Laureate, V. L. Ginzburg. I earned my Ph.D. in 1977 from Lebedev Physics Institute working with Dr. Khomskii and received my B.S./M.S. from Lomonosov University in Moscow, majoring in Physics and Mathematics.
From 1984 to 1993 I was a Senior Scientist in the Institute of Atomic Energy in Armenia, where I was responsible for the development of various programs in applications of synchrotron radiation sources for studies of solid state physics, properties of novel high temperature superconductors, electronic phase transitions in rare-earth and transition metal compounds. Since 1984 I was appointed as Professor in General Physics Department at the Armenia University in Yerevan, where I have developed a contemporary educational program and introduced new tutorials and textbooks for graduates in the areas of Quantum Magnetism and Superconductivity.
In 1993 I was invited to work in the United States, particularly at Union College (Schenectady, NY) to join the Department of Physics (http://www.union.edu/academic_depts/physics_astronomy/index.php) as a Research Professor. There I developed a theory of orbital ordering and mixed valence states in extreme external conditions (temperature, pressure, composition of material) and studied the finite size effects in small clusters of atoms in the presence of strong magnetic field. Since 1996 I was invited by CSUN to work as a Research Associate in the Material Computational Center where I worked on different projects on electron correlations in solid materials. I have developed theory of electron correlations for accurate calculations of the electronic properties of novel magnetic and superconducting materials.
I was working as an Adjunct Professor and Part Time Faculty at the Department of Physics at CSUN and Pierce College, where I was involved in teaching the number of lecture courses and laboratory sessions in general physics. Also at CSUN I was pursuing my research work in theoretical and computational physics in collaboration with my colleagues, Dr. C. Yang, You-Ling Chiang at the Tamkang University in Taiwan by applying newly developed many body self-consistent perturbation theory beyond the existing self-consisting theories for studies of Fermi and Luttinger liquids, high temperature superconductivity, the BCS-Bose condensation crossover, etc.
Since 2006 I started to teach physics courses and purue my research work at the Department of Physics and Astronomy in California State University, Los Angeles (CSULA). My most recent research in area of nanoscience with my colleagues Dr. G. Fernando and K. Palandage from University of Connecticut and Dr. J. Davenport in Brookhaven Natioonal Laboratory is on electron pairing and formation of various types of magnetic correlations for ensembles of small clusters of different geometries are studied with emphasis on tetrahedrons and square pyramids under variation of interaction strength, electron doping and temperature. These exact calculations of charge and spin collective excitations and pseudogaps yield intriguing insights into level crossing degeneracies, phase separation and condensation. Obtained coherent and incoherent pairings provide a route for possible superconductivity different from the conventional BCS theory. Criteria for spin-charge separation, reconciliation and recombination driven by interaction strength, next-nearest coupling and temperature are found. Resulting phase diagrams resemble a number of inhomogeneous, coherent and incoherent nanoscale phases seen recently in high-Tc cuprates, manganites and colossal magnetoresistive (CMR) nanomaterials.
I have around 30 years of professional experience in the area of Applied and Theoretical Physics, Material Sciences and have published more than 100 papers in refereed scientific periodicals.
