Abstract:
Weakly interacting, dilute atomic Bose-Einstein condensates (BECs) have proved to be an attractive context for the study of nonlinear dynamics and quantum effects at the macroscopic scale. Recently, atomic BECs have been used to investigate quantum turbulence both experimentally and theoretically, stimulated largely by the high degree of control which is available within these quantum gases.   I shall motivate the use of atomic BECs for the study of quantum turbulence and further discuss our theoretical investigations into laser stirring as a route to the generation of an isotropic vortex tangle for the study of quantum turbulence in this scenario.  The results presented are obtained using the Gross-Pitaevskii equation.

 

Looking forward to seeing many of you at the seminar.
