Double Well Physics

With the introduction of RF-induced potentials, building double well traps has become a robust standard technology in our setup. Typically, pairs of Bose gases in the one-dimensional and 1D-3D-crossover regimes are prepared by either splitting a single degenerate cloud or cooling a cloud into a double well trap, creating fully independent clouds, the signature of which is a random phase in interferometry.

We use this technique for studies ranging from integrated matter-wave interferometry to fundamental studies on elongated Bosonic Josephson Junctions. Inclusion of optimal control techniques is planned.
