Galilean boosts and superfluidity of resonantly driven polariton fluids in the presence of an incoherent reservoir
Ivan Amelio, Anna Minguzzi, Maxime Richard +1
We theoretically investigate how the presence of a reservoir of incoherent excitations affects the superfluidity properties of resonantly driven polariton fluids. While in the abse…
Theory of the coherence of topological lasers
Ivan Amelio, Iacopo Carusotto
We present a theoretical study of the temporal and spatial coherence properties of a topological laser device built by including saturable gain on the edge sites of a Harper--Hofst…
New perspectives on superfluidity in resonantly--driven polariton fluids
Ivan Amelio, Iacopo Carusotto
In this paper we discuss, within the Gross--Pitaevskii framework, superfluidity, soliton nucleation, and instabilities in a non-equilibrium polariton fluid injected by a spatially…
Dispersion relation of the collective excitations in a resonantly driven polariton fluid
Petr Stepanov, Ivan Amelio, Jean-Guy Rousset +6
Exciton-polaritons in semiconductor microcavities constitute the archetypal realization of a quantum fluid of light. Under coherent optical drive, remarkable effects such as superf…
Probing quantum turbulence in He by quantum evaporation measurements
Ivan Amelio, Davide Emilio Galli, Luciano Reatto
Theory of superfluid He shows that, due to strong correlations and backflow effects, the density profile of a vortex line has the character of a density modulation and it is no…
