Abstract
|
|
|
|
| We study the vortex dynamics of a quantum-degenerate Bose gas through the intensity fluctuations of the interference from particles extracted at two different positions. It is shown numerically with classical field simulations that an interacting Bose gas with proliferating vortices exhibits long correlation times for these intensity fluctuations. This behavior is contrasted with the case of a noninteracting gas, which we describe analytically, and with the case of a well-condensed Bose gas without vortices. We discuss the observability of our predictions in quantum fluids of exciton-polaritons. |
