Vortex lattices of bosons in deep rotating optical lattices
arXiv:0710.1090 · doi:10.1103/PhysRevA.77.033629
Abstract
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 transitions where vortices are pinned with their cores only on plaquettes or only on sites. We discuss connections between these vortex structures and the Hofstadter-butterfly spectrum of free particles on a rotating lattice.
