Chaoticity without thermalisation in disordered lattices
O. Tieleman, Ch. Skokos, A. Lazarides
We study chaoticity and thermalization in Bose-Einstein condensates in disordered lattices, described by the discrete nonlinear Schrödinger equation (DNLS). A symplectic integratio…
Non-Abelian gauge fields and topological insulators in shaken optical lattices
Philipp Hauke, Olivier Tieleman, Alessio Celi +8
Time-periodic driving like lattice shaking offers a low-demanding method to generate artificial gauge fields in optical lattices. We identify the relevant symmetries that have to b…
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…
Supersolid phases of dipolar bosons in optical lattices with a staggered flux
O. Tieleman, A. Lazarides, C. Morais Smith
We present the theoretical mean-field zero-temperature phase diagram of a Bose-Einstein condensate (BEC) with dipolar interactions loaded into an optical lattice with a staggered f…
