Generalized kinetic equations of dynamic system interacting with non-equilibrium medium
Mikheil Zviadadze, Alexander kvirikadze
The behavior of dynamical system interacting with non-equilibrium medium is investigated. Formally exact kinetic equations are derived for the statistical operator of the dynamical…

Obtaining and Application of the Reduced Bloch Equations
M. D. Zviadadze, N. D. Chachava, A. G. Kvirikadze +1
Well-known Bloch equations describe the spin systems (electronic and nuclear) for any scale of time, from transient processes to steady states. Usually in solids T_2 << T_1. The qu…
