Spatiotemporal scaling of two-dimensional nonequilibrium exciton-polariton systems with weak interactions
Quanyu Mei, Kai Ji, Michiel Wouters
We perform a numerical study on the two-dimensional nonequilibrium exciton-polariton systems driven by incoherent pumping based on the stochastic generalized Gross-Pitaevskii equat…
Spectral weight suppression in response functions of ultracold fermion-boson mixtures
Kai Ji, Andreas Komnik
We study the dynamical response of ultracold fermion-boson mixture in the Bogoliubov regime, where the interactions between fermionic impurities and bosonic excitations (phonons) a…
Temporal coherence of one-dimensional non-equilibrium quantum fluids
Kai Ji, Vladimir N. Gladilin, Michiel Wouters
We theoretically investigate the time dependence of the first order coherence function for a one-dimensional driven dissipative non-equilibrium condensate. Simulations on the gener…
The spatial coherence of weakly interacting one-dimensional non-equilibrium Bosonic quantum fluids
Vladimir N. Gladilin, Kai Ji, Michiel Wouters
We present a theoretical analysis of spatial correlations in a one-dimensional driven-dissipative non-equilibrium condensate. Starting from a stochastic generalized Gross-Pitaevski…
Dynamical response of ultracold interacting fermion-boson mixtures
Kai Ji, Stefan Maier, Andreas Komnik
We analyze the dynamical response of a ultracold binary gas mixture in presence of strong boson-fermion couplings. Mapping the problem onto that of the optical response of a metal/…
