Elementary excitations of chiral Bose-Einstein condensates
Matthew Edmonds, Manuel Valiente, Patrik Öhberg
We study the collective modes of a Bose-Einstein condensate subject to an optically induced density-dependent gauge potential. The corresponding interacting gauge theory lacks Gali…
Engineering the Dynamics of Effective Spin-Chain Models for Strongly Interacting Atomic Gases
A. G. Volosniev, D. Petrosyan, M. Valiente +3
We consider a one-dimensional gas of cold atoms with strong contact interactions and construct an effective spin-chain Hamiltonian for a two-component system. The resulting Heisenb…
Low-energy behaviour of strongly-interacting bosons on a flat-banded lattice above the critical filling factor
Lawrence G. Phillips, Gabriele De Chiara, Patrik Öhberg +1
Bosons interacting repulsively on a lattice with a flat lowest band energy dispersion may, at sufficiently small filling factors, enter into a Wigner-crystal-like phase. This phase…
