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…

Discrete breathers in classical spin lattices
Y. Zolotaryuk, S. Flach, V. Fleurov
Discrete breathers (nonlinear localised modes) have been shown to exist in various nonlinear Hamiltonian lattice systems. In the present paper we study the dynamics of classical sp…
