Bogoliubov excitations driven by thermal lattice phonons in a quantum fluid of light
Irénée Frérot, Amit Vashisht, Martina Morassi +5
The elementary excitations in weakly interacting quantum fluids have a non-trivial nature which is at the basis of defining quantum phenomena such as superfluidity. These excitatio…
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…
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…
Phonon mediated conversion of exciton-polaritons Rabi oscillation into THz radiation
Katharina Rojan, Yoan Leger, Giovanna Morigi +2
Semiconductor microcavities in the strong-coupling regime exhibit an energy scale in the THz frequency range, which is fixed by the Rabi splitting between the upper and lower excit…
