--- res: bibo_abstract: - Anisotropic dipole-dipole interactions between ultracold dipolar fermions break the symmetry of the Fermi surface and thereby deform it. Here we demonstrate that such a Fermi surface deformation induces a topological phase transition - the so-called Lifshitz transition - in the regime accessible to present-day experiments. We describe the impact of the Lifshitz transition on observable quantities such as the Fermi surface topology, the density-density correlation function, and the excitation spectrum of the system. The Lifshitz transition in ultracold atoms can be controlled by tuning the dipole orientation and, in contrast to the transition studied in crystalline solids, is completely interaction driven.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Erik foaf_name: Van Loon, Erik foaf_surname: Van Loon - foaf_Person: foaf_givenName: Mikhail foaf_name: Katsnelson, Mikhail foaf_surname: Katsnelson - foaf_Person: foaf_givenName: Lauriane foaf_name: Chomaz, Lauriane foaf_surname: Chomaz - foaf_Person: foaf_givenName: Mikhail foaf_name: Lemeshko, Mikhail foaf_surname: Lemeshko foaf_workInfoHomepage: http://www.librecat.org/personId=37CB05FA-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0002-6990-7802 bibo_doi: 10.1103/PhysRevB.93.195145 bibo_issue: '19' bibo_volume: 93 dct_date: 2016^xs_gYear dct_language: eng dct_publisher: American Physical Society@ dct_title: Interaction-driven Lifshitz transition with dipolar fermions in optical lattices@ ...
