Description/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 brie
y 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
