Kicked Bose-Einstein condensates: in search of exponential instability

Kicked Bose-Einstein condensates: in search of exponential instability
Kicked Bose-Einstein condensates: in search of exponential instability
Bose-Einstein condensates subject to short pulses (`kicks') from standing waves of light represent a nonlinear analogue of the well-known chaos paradigm, the quantum kicked rotor. We review briefly our current understanding of dynamical
or exponential instability in weakly kicked BECs. Previous studies of the onset of dynamical instability associated it with some form of classical chaos. We show it is due to parametric instability : resonant driving of certain collective modes. We map the zones of instability and calculate the Liapunov exponents.

Abstract

Bose-Einstein condensates subject to short pulses (`kicks') from standing waves of light represent a nonlinear analogue of the well-known chaos paradigm, the quantum kicked rotor. We review briefly our current understanding of dynamical
or exponential instability in weakly kicked BECs. Previous studies of the onset of dynamical instability associated it with some form of classical chaos. We show it is due to parametric instability : resonant driving of certain collective modes. We map the zones of instability and calculate the Liapunov exponents.
