Armen Norair Kocharian (Armenian: Արմեն Քոչարյան; born January 3, 1948, in Yerevan, Armenia) is an Armenian physicist and senior research scientist specializing in nanoscience, nanomaterials, and condensed matter physics. His work encompasses correlated electrons, critical phenomena, superconductivity, magnetism, and earthquake studies. He is a professor of physics and astronomy at California State University, Los Angeles.
Early life and education
Kocharian was born on January 3, 1948, in Yerevan, Armenia. In 1966, he enrolled in the physics department of Yerevan State University and later transferred to Lomonosov Moscow State University in 1969. He graduated summa cum laude in 1973 with a Bachelor of Science and Master of Science in theoretical physics. He subsequently completed his Ph.D. in solid-state physics at the Lebedev Physics Institute under the supervision of Prof. Daniel Khomskii, focusing on high-temperature superconductivity. In 1991, he earned a second doctoral degree (Doctor of Sciences) in physics and mathematics, equivalent to a professorship in the United States, awarded by the Supreme Attestation Board in Moscow.
Career
Kocharian began his career as a principal investigator on projects funded by the Ministry of Atomic Energy, focusing on the applications of synchrotron radiation sources for studying rare earth materials and transition metal oxides. In 1993, he moved to the United States as a visiting professor at Union College, Schenectady, New York. From 1996, he worked at California State University, Northridge, as part of the W.M. Keck Computational Materials Theory Center, contributing to theoretical physics and developing computational techniques for studying materials with strong electron correlations.
Currently, Kocharian is a professor at California State University, Los Angeles, in the Department of Physics and Astronomy. His research has contributed to experimental and theoretical studies of electron instabilities, phase transitions, and nanomaterials. Notable contributions include:
- Development of a bottom-up approach to studying electron instabilities in nanoclusters.
- Insights into the physics of high-temperature superconductivity, ferromagnetism, and ultracold fermionic atoms.
- Collaborative research with institutions like Los Alamos National Laboratory, Sandia National Laboratories, and Brookhaven National Laboratory.
- Kocharian has authored over 200 peer-reviewed articles, review papers, and book chapters, and serves as a peer reviewer for several prestigious journals, including Physics Letters A and Journal of Nanoparticle Research.
Research Areas
Kocharian’s research focuses on:
- Nanomaterials and Nanoscience: Studies of electron pairing, phase separation, and inhomogeneities in nanoclusters and bulk materials.
- Condensed Matter Physics: Investigations into superconductivity, magnetism, and critical phenomena.
- Seismology: Modeling the critical behavior of seismic systems and earthquake dynamics.
- Spintronics: Exploring spin-polarized properties of semiconductors and heterojunctions.
Personal life
Kocharian is married to Hasmik Agadjanian, and they have three children: Vahan, David, and Adrina. His father, Norair M. Kocharian, was a prominent physicist and a founding member of the Aragats Cosmic Ray Research Station. His brother, Karen Kocharian, is a radio physicist and senior engineer at Veoneer Co. in Lowell, Massachusetts.
