Chaotic dynamics of a double-well Bose-Einstein condensate

We study the dynamics of a double-well BEC system subjected to oscillating dissipation. The macroscopic model is described within the mean-field approximation while the noise effect due to large reservoir fluctuation has been averaged out to zero. We chose a simple dissipative memory kernel to produce a time-dependent oscillating dissipation. Our numerically calculated phase-space portraits and Lyapunov exponents show an enhanced route to chaos as one increases the driving dissipation amplitude.
