Quantum fluids of light merge many-body physics and nonlinear optics, revealing quantum
hydrodynamic features of light when it propagates in nonlinear media. One of the most …

We study analytically an analog of the Andreev reflection at a normal-superfluid interface.
The polariton gapped superfluid region is achieved by quasiresonant optical pum**. The …

We propose an experimental setup that should make it possible to reveal the frictionless flow
of a superfluid of light from the suppression of the drag force that it exerts on a material …

We determine in a nonperturbative way the critical velocity for superfluidity of a generic
quantum fluid flowing past a localized obstacle in the one-dimensional mean-field regime …

Motivated by recent experiments on generation of wave patterns by a polariton condensate
incident on a localized obstacle, we study the characteristics of such flows under the …

We theoretically investigate how the presence of a reservoir of incoherent excitations affects
the superfluidity properties of resonantly driven polariton fluids. While in the absence of …

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 …

Abstract This thesis presents an experimental study of hydrodynamical phenomena of a
laser propagating nonlinearly. For a medium presenting an intensity-dependent refractive …

We study the hydrodynamics of a nonresonantly pumped polariton condensate in a quasi-
one-dimensional quantum wire taking into account the spin degree of freedom. We clarify …

Quantum fluids of light are the photonic counterpart of Bose gases. They currently attract
increasing interest since they are versatile and highly tunable systems for probing many …
