Coherent splitting of two-dimensional Bose gases in magnetic potentials
New Journal of Physics IOP Publishing 22:10 (2020) 103040
Abstract:
Investigating out-of-equilibrium dynamics with two-dimensional (2D) systems is of widespread theoretical interest, as these systems are strongly influenced by fluctuations and there exists a superfluid phase transition at a finite temperature. In this work, we realise matter-wave interference for degenerate Bose gases, including the first demonstration of coherent splitting of 2D Bose gases using magnetic trapping potentials. We improve the fringe contrast by imaging only a thin slice of the expanded atom clouds, which will be necessary for subsequent studies on the relaxation of the gas following a quantum quench.Coherent splitting of two-dimensional Bose gases in magnetic potentials
