Bromley, M. W. J.Esry, B. D.2023-12-072023-12-072004-07-12https://hdl.handle.net/2097/43670The possibility of generating vortices during matter-wave propagation through microstructures is examined. Vortices can arise solely due to wave interference in low-density ultracold atom clouds, and do not require any atom–atom (nonlinear) interactions. The properties of these “interference vortices” are understood from a simple two-mode model in a straight waveguide. This model is then applied to vortex creation in a circular bend since a circular waveguide bend is one of the simplest atom optical elements that can induce mode excitations. Time-independent and time-dependent analyses are used to investigate vortex creation and dynamics in these systems.© American Physical Society (APS).
