English abstract:
We realize a one-dimensional Josephson junction using quantum degenerate Bose gases in a tunable
double well potential on an atom chip. Matter wave interferometry gives direct access to the relative phase
field, which reflects the interplay of thermally driven fluctuations and phase locking due to tunneling.
The thermal equilibrium state is characterized by probing the full statistical distribution function of the
two-point phase correlation. Comparison to a stochastic model allows us to measure the coupling strength
and temperature and hence a full characterization of the system.
