Gutzwiller Monte Carlo approach for a critical dissipative spin model

Wim Casteels, Ryan M. Wilson, Michiel Wouters

We use the Gutzwiller Monte Carlo approach to simulate the dissipative XYZ-model in the vicinity of a dissipative phase transition. This approach captures classical spatial correla…

Probing a dissipative phase transition via dynamical optical hysteresis

S. R. K. Rodriguez, W. Casteels, F. Storme +8

We experimentally explore the dynamic optical hysteresis of a semiconductor microcavity as a function of the sweep time. The hysteresis area exhibits a double power law decay due t…

Probing photon correlations in the dark sites of geometrically frustrated cavity lattices

W. Casteels, R. Rota, F. Storme +1

We theoretically explore the driven-dissipative physics of geometrically frustrated lattices of cavity resonators with relatively weak nonlinearities, i.e. a photon-photon interact…

Many-polaron description of impurities in a Bose-Einstein condensate in the weak coupling regime

W. Casteels, J. Tempere, J. T. Devreese

The weak coupling many-polaron formalism is applied to the case of the polaronic system consisting of impurities in a Bose-Einstein condensate. This allows to investigate the groun…

Strong coupling treatment of the polaronic system consisting of an impurity in a condensate

W. Casteels, T. Van Cauteren, J. Tempere +1

The strong coupling treatment of the Fröhlich-type polaronic system, based on a canonical transformation and a standard Landau-Pekar type variational wave function, is applied to t…

Feynman path-integral treatment of the BEC-impurity polaron

J. Tempere, W. Casteels, M. K. Oberthaler +2

The description of an impurity atom in a Bose-Einstein condensate can be cast in the form of Frohlich's polaron Hamiltonian, where the Bogoliubov excitations play the role of the p…
