Skyrmions in a ferromagnetic Bose-Einstein condensate
U. Al Khawaja, H. T. C. Stoof
The recently realized multicomponent Bose-Einstein condensates provide opportunities to explore the rich physics brought about by the spin degrees of freedom. For instance, we can…
Quantum phases in an optical lattice
D. van Oosten, P. van der Straten, H. T. C. Stoof
We present the zero-temperature phase diagram of bosonic atoms in an optical lattice, using two different mean-field approaches. The phase diagram consists of various insulating ph…
Explosion of a collapsing Bose-Einstein condensate
R. A. Duine, H. T. C. Stoof
We show that elastic collisions between atoms in a Bose-Einstein condensate with attractive interactions lead to an explosion that ejects a large fraction of the collapsing condens…
Kinetic Theory of Collective Excitations and Damping in Bose-Einstein Condensed Gases
U. Al Khawaja, H. T. C. Stoof
We calculate the frequencies and damping rates of the low-lying collective modes of a Bose-Einstein condensed gas at nonzero temperature. We use a complex nonlinear Schrödinger equ…
Skyrmions in spinor Bose-Einstein condensates
H. T. C. Stoof
We show that spinor Bose-Einstein condensates not only have line-like vortex excitations, but in general also allow for point-like topological excitations, i.e., skyrmions. We disc…
