Impurities in a one-dimensional Bose gas: the flow equation approach

Autor: Brauneis, F., Hammer, H. -W., Lemeshko, M., Volosniev, A. G.

Publikováno v: SciPost Phys. 11, 008 (2021)

A few years ago, flow equations were introduced as a technique for calculating the ground-state energies of cold Bose gases with and without impurities. In this paper, we extend this approach to compute observables other than the energy. As an exampl

Diagrammatic Monte Carlo approach to angular momentum in quantum many-particle systems

Autor: Bighin, G., Tscherbul, T. V., Lemeshko, M.

Publikováno v: Phys. Rev. Lett. 121, 165301 (2018)

We introduce a Diagrammatic Monte Carlo (DiagMC) approach to angular momentum properties of quantum many-particle systems possessing a macroscopic number of degrees of freedom. The treatment is based on a diagrammatic expansion that merges the usual

Interaction-driven Lifshitz transition with dipolar fermions in optical lattices

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 -- so-called Lif
