Spontaneous breaking of time translation symmetry in a system without periodic external driving
T. T. Sergeev, A. A. Zyablovsky, E. S. Andrianov +1
It is known that the spontaneous time translation symmetry breaking can occur in systems periodically driven at a certain period. We predict a spontaneous breaking of time translat…

Self-consistent description of relaxation processes in systems with ultra- and deep-strong coupling
T. T. Sergeev, A. A. Zyablovsky, E. S. Andrianov +1
An ultra-strong coupling regime takes place in a compound system when a coupling strength between the subsystems exceeds one tenth of the system eigenfrequency. It transforms into…
