Since 2006, the head of the Department of General and Theoretical Physics at the Russian-Armenian (Slavic) University. 2012-2018, the director of the Institute of Mathematics and High Technologies of the Russian-Armenian University. 2018- 2023, the chief scientific adviser of the Russian-Armenian University, since 2023, the chief adviser to the rector of the Russian-Armenian University. • Scientific activity
The main areas of scientific activity of Kazaryan are: solid state physics, optical properties of semiconductors, issues of exciton physics, physics of low-dimensional semiconductor systems (nanostructures). In particular, he proposed a new plasmonic mechanism of optical absorption in semiconductors, proved the possibility of single-phonon absorption in a size-quantized system. Recent studies are devoted to the theory of electronic and optical properties of nanostructures of complex geometry and for various models of limited potential. In the early 1990s, Kazaryan first initiated studies of the physical properties of quantum dots of ellipsoidal geometry. At the same time, he formed a new class of problems - the study of physical phenomena in quantum dots of nontrivial geometry (ellipsoidal, lenticular, conical). The calculations were based on the stationary adiabatic method due to the special geometry of the systems under study. In parallel with the class of problems mentioned, edited by. Kazaryan and his students have conducted intensive studies of the electronic and optical properties of spherical and cylindrical nanosheets, as well as quantum rings.
