Cold Atoms

This area of research focuses on the study of equilibrium phase diagrams and
nonequilibrium dynamics of cold atoms. These systems offer a large degree of
tunability and are essentially disorder-free [1]. One can thus address experi-
mentally a number of fundamental questions without having to face the typical
complications of solid-state environments. The work reported below has been
done in collaboration with several people, including K. Capelle (IFSC, Bra-
zil), M. Cazalilla (CSIC-UPV/EHU, Donostia-San Sebastian, Spain), C. Kollath
(Ecole Polytechnique, France), X. Gao (Zhejiang Normal University, China),
and G. Vignale (University of Missouri-Columbia, USA).
Equilibrium phase diagrams
In Ref. [2] we have studied by means of
the density-matrix renormalization-group
(DMRG) technique a two-component
atomic Fermi gas with attractive inter-
actions inside a 1D optical lattice. We
have demonstrated how this system ex-
hibits phases characterized by atomic-
