Few-Body Route to One-Dimensional Quantum Liquids
Manuel Valiente, Patrik Ohberg
Gapless many-body quantum systems in one spatial dimension are universally described by the Luttinger liquid effective theory at low energies. Essentially, only two parameters ente…
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…
