Commensurability and hysteretic evolution of vortex configurations in rotating optical lattices
Daniel S. Goldbaum, Erich J. Mueller
We present a theoretical study of vortices within a harmonically trapped Bose-Einstein condensate in a rotating optical lattice. Due to the competition between vortex-vortex intera…
Vortices near the Mott phase of a trapped Bose-Einstein condensate
Daniel S. Goldbaum, Erich J. Mueller
We present a theoretical study of vortices within a harmonically trapped Bose-Einstein condensate in a rotating optical lattice. We find that proximity to the Mott insulating state…
Vortices in rotating optical lattices: commensurability, hysteresis, and proximity to the Mott State
Daniel S. Goldbaum, Erich J. Mueller
Quantized vortices stunningly illustrate the coherent nature of a superfluid Bose condensate of alkali atoms. Introducing an optical lattice depletes this coherence. Consequently,…
Vortex lattices of bosons in deep rotating optical lattices
Daniel S. Goldbaum, Erich J. Mueller
We study vortex-lattice phases for a Bose gas trapped in a rotating optical-lattice near the superfluid--Mott-insulator transition. We find a series of abrupt structural phase tran…
