Broken space-time symmetries and mechanisms of rectification of ac fields by nonlinear (non)adiabatic response
S. Denisov, S. Flach, A. A. Ovchinnikov +2
We consider low-dimensional dynamical systems exposed to a heat bath and to additional ac fields. The presence of these ac fields may lead to a breaking of certain spatial or tempo…

Tunneling of localized excitations: giant enhancement due to fluctuations
S. Flach, V. Fleurov, A. A. Ovchinnikov
We consider the tunneling of localized excitations (many boson bound states) in the presence of a bosonic bath. We show both analytically and numerically that the bath influence re…

Static magnetization induced by time-periodic fields with zero mean
S. Flach, A. A. Ovchinnikov
We consider a single spin in a constant magnetic field or an anisotropy field. We show that additional external time-periodic fields with zero mean may generate nonzero time-averag…
