The phenomenon of stochastic resonance (SR) is known to occur mostly in bistable systems.
However, the question of occurrence of SR in periodic potential systems is not conclusively resolved.Our pres...
Anomalous Bloch oscillations in one dimensional parity-breaking periodic potentials
Anomalous Bloch oscillations dimensional parity-breaking periodic potentials

We investigate the dynamics of a wave packet in a parity-breaking one-dimensional periodic
potential slowly varied in time and perturbed by a linear potential. Parity is broken by considering an asym...

We report wide class of exact solutions of the modified Gross-Pitaevskii equation (GPE) in `smart' Jacobi elliptic potentials: $V(\xi)=-V_{0}{\rm sn(\xi,m)}$, $V(\xi)=-V_{0}{\rm cn(\xi,m)}$, and $V(\x...
