Finite-momentum Bose-Einstein condensates in shaken 2D square optical lattices
M. Di Liberto, O. Tieleman, V. Branchina +1
We consider ultracold bosons in a 2D square optical lattice described by the Bose-Hubbard model. In addition, an external time-dependent sinusoidal force is applied to the system,…

Strongly interacting bosons in a 1D optical lattice at incommensurate densities
Achilleas Lazarides, Olivier Tieleman, Cristiane Morais Smith
We investigate quantum phase transitions occurring in a system of strongly interacting ultracold bosons in a 1D optical lattice. After discussing the commensurate-incommensurate tr…
