Dynamical Instabilities

The onset of dynamical instabilities of Bose–Einstein condensates in optical lattices due to the dephasing of the condensate wavefunction is observed through the decay of the visibility of the interference pattern in time-of-flight and the growth of the radial width of the condensate.
