We study the population dynamics of a Bose-Einstein condensate in a double-well potential throughout the crossover from Josephson dynamics to hydrodynamics. At barriers higher than the chemical potential, we observe slow oscillations well described by a Josephson model. In the limit of low barriers, the fundamental frequency agrees with a simple hydrodynamic model, but we also observe a second, higher frequency. A full numerical simulation of the Gross-Pitaevskii equation giving the frequencies…

An empirical model based on the analogy with the anharmonic oscillator is proposed to describe the effect of various experimental parameters on the nonequilibrium tunnel dynamics of two coupled one-dimensional Bose-Einstein quasicondensates deep in the Josephson regime.

It is shown that the damping of the Josephson oscillations originates from the quantum and thermal fluctuations intrinsically present in the strongly correlated gas, which depends on barrier height, interaction strength, and temperature.
