Nomlinear Hall effect in a time-periodic electric field and related phenomena
A. A. Ovchinnikov
A motion of neutral and charged particles located nearby a metal surface under joint action of time-periodic electric field E(t) directed normally to the surface and permanent magn…
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…
AC-driven quantum spins: resonant enhancement of transverse DC magnetization
S. Flach, A. E. Miroshnichenko, A. A. Ovchinnikov
We consider s=1/2 spins in the presence of a constant magnetic field in z-direction and an AC magnetic field in the x-z plane. A nonzero DC magnetization component in y direction i…
Rectification of current in ac-driven nonlinear systems and symmetry properties of the Boltzmann equation
O. Yevtushenko, S. Flach, Y. Zolotaryuk +1
We study rectification of a current of particles moving in a spatially periodic potential under the influence of time-periodic forces with zero mean value. If certain time-space sy…
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…
