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…
Diagrammatic Monte Carlo algorithm for the resonant Fermi gas
K. Van Houcke, F. Werner, T. Ohgoe +2
We provide a description of a diagrammatic Monte Carlo algorithm for the resonant Fermi gas in the normal phase. Details are given on diagrammatic framework, Monte Carlo moves, and…
Contact and Momentum Distribution of the Unitary Fermi Gas
R. Rossi, T. Ohgoe, E. Kozik +4
A key quantity in strongly-interacting resonant Fermi gases is the contact , which characterizes numerous properties such as the momentum distribution at large momenta…
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…
Feynman diagrams versus Fermi-gas Feynman emulator
K. Van Houcke, F. Werner, E. Kozik +7
Precise understanding of strongly interacting fermions, from electrons in modern materials to nuclear matter, presents a major goal in modern physics. However, the theoretical desc…
