Negative drag in nonequilibrium polariton quantum fluids
Mathias Van Regemortel, Michiel Wouters
The possibility of a negative drag force on a defect in nonequilibrium polariton quantum fluids is presented. We relate this phenomenon to the selective parametric amplification of…
Polychromatic polariton laser selector switch
G. Grosso, S. Trebaol, M. Wouters +3
Integration of optical elements into scalable chips has been at the center of a large effort in recent years. Concurrently, the separation between the diverse functions, namely swi…
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…
Probing few-particle Laughlin states of photons via correlation measurements
R. O. Umucalilar, M. Wouters, I. Carusotto
We propose methods to create and observe Laughlin-like states of photons in a strongly nonlinear optical cavity. Such states of strongly interacting photons can be prepared by pump…
Heterodyne Spectroscopy of Polariton Spinor Interactions
Naotomo Takemura, Stéphane Trebaol, Michiel Wouters +2
We report on spinor polariton interactions in GaAs based microcavities. This investigation is carried out by means of heterodyne polarized pump-probe spectroscopy. We show the depe…
Ultrafast tristable spin memory of a coherent polariton gas
Roland Cerna, Yoan Léger, Taofiq K. Paraïso +4
Nonlinear interactions in coherent gases are not only at the origin of of bright and dark solitons and superfluids. At the same time, they give rise to phenomena such as multistabi…
