Exact homogeneous equations for a relevant part of the two-time equilibrium correlation function for the dynamic variables of a subsystem interacting with a boson field (heat bath) are obtained. The developed approach is applied to the Fr?hlich polaron and the low-temperature polaron mobility is found with a correction due to initial correlations. Quasistatic behavior of strongly coupled vortex pairs with parallel cores polarization and antiparallel chiralities (P-AP state) has been studied experimentally, analytically and by numerical simulation taking into consideration pinning effects. The obtained results can be the base for the development of new generation of ultrafast information processing. Product Description popup.authors Іванов Б.О. Білоколос Є.Д. Бондаренко П.В.
