Diagrammatic Monte Carlo study of the acoustic and the BEC polaron
Jonas Vlietinck, Wim Casteels, Kris Van Houcke +3
We consider two large polaron systems that are described by a Fröhlich type of Hamiltonian, namely the Bose-Einstein condensate (BEC) polaron in the continuum and the acoustic pola…
Diagrammatic Monte Carlo study of the Fermi polaron in two dimensions
Jonas Vlietinck, Jan Ryckebusch, Kris Van Houcke
We study the properties of the two-dimensional Fermi polaron model in which an impurity attractively interacts with a Fermi sea of particles in the zero-range limit. We use a diagr…
Quasiparticle properties of an impurity in a Fermi gas
Jonas Vlietinck, Jan Ryckebusch, Kris Van Houcke
We report on a study of a spin-down impurity strongly coupled to a spin-up Fermi sea (a so-called Fermi polaron) with the diagrammatic Monte-Carlo (DiagMC) technique. Conditions of…
