Hysteresis and metastability of Bose-Einstein condensed clouds of atoms confined in ring potentials
arXiv:1412.4512 · doi:10.1103/PhysRevA.91.023613
Abstract
We consider a Bose-Einstein condensed cloud of atoms which rotate in a toroidal/annular potential. Assuming one-dimensional motion, we evaluate the critical frequencies associated with the effect of hysteresis and the critical coupling for stability of the persistent currents. We perform these calculations using both the mean-field approximation and the method of numerical diagonalization of the many-body Hamiltonian which includes corrections due to the finiteness of the atom number.
