As a third year student of
Irkutsk State Univeristy
in 1991 I join theoretical physics department. I started
comprehend physics from neutrino oscillations. In collaboration
with Dr. V. A. Naumov and Dr. S. E. Korenblit I studied
an evolution of non-Hermitian Hamiltonian of three-level system
and an effect of Berry's phases on neutrino oscillation.
In 1995 I joined a project of V. M. Dubovik, an investigation of
third electromagnetic characteristic of neutrino, its toroid
dipole moment.
