Critical dynamical properties of a first-order dissipative phase transition
Wim Casteels, Rosario Fazio, Cristiano Ciuti
We theoretically investigate the critical properties of a single driven-dissipative nonlinear photon mode. In a well-defined thermodynamical limit of large excitation numbers, the…
Exact steady state of a Kerr resonator with one- and two-photon driving and dissipation: Controllable Wigner-function multimodality and dissipative phase transitions
Nicola Bartolo, Fabrizio Minganti, Wim Casteels +1
We present exact results for the steady-state density matrix of a general class of driven-dissipative systems consisting of a nonlinear Kerr resonator in the presence of both coher…
Quantum entanglement in the spatial symmetry breaking phase transition of a driven-dissipative Bose-Hubbard dimer
Wim Casteels, Cristiano Ciuti
We theoretically explore quantum correlation properties of a dissipative Bose-Hubbard dimer in presence of a coherent drive. In particular, we focus on the regime where the semicla…
Polaron formation in the vicinity of a narrow Feshbach resonance in atomic and exciton-polariton condensates
Wim Casteels, Michiel Wouters
The polaronic system consisting of an impurity in a dilute Bose-Einstein condensate is considered in the presence of a narrow Feshbach resonance. For this purpose a coupled-channel…
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…
Bipolarons and multi-polarons consisting of impurity atoms in a Bose-Einstein condensate
W. Casteels, J. Tempere, J. T. Devreese
The variational Feynman formalism for the polaron, extended to an all-coupling treatment of bipolarons, is applied for two impurity atoms in a Bose-Einstein condensate. This shows…
