Observation of Superfluidity of Polaritons in Semiconductor Microcavities
A. Amo, J. Lefrere, S. Pigeon +6
One of the most striking manifestations of quantum coherence in interacting boson systems is superfluidity. Exciton-polaritons in semiconductor microcavities are two-dimensional co…
Probing the excitation spectrum of nonresonantly pumped polariton condensates
Michiel Wouters, Iacopo Carusotto
We propose a four wave mixing experiment to probe the elementary excitation spectrum of a non-equilibrium Bose-Einstein condensate of exciton-polaritons under non-resonant pumping.…
Observation of long-lived polariton states in semiconductor microcavities across the parametric threshold
D. Ballarini, D. Sanvitto, A. Amo +5
The excitation spectrum around the pump-only stationary state of a polariton optical parametric oscillator (OPO) in semiconductor microcavities is investigated by time-resolved pho…
Numerical observation of Hawking radiation from acoustic black holes in atomic Bose-Einstein condensates
Iacopo Carusotto, Serena Fagnocchi, Alessio Recati +2
We report numerical evidence of Hawking emission of Bogoliubov phonons from a sonic horizon in a flowing one-dimensional atomic Bose-Einstein condensate. The presence of Hawking ra…
Quantised Vortices in an Exciton-Polariton Fluid
K. G. Lagoudakis, M. Wouters, M. Richard +5
One of the most striking quantum effects in a low temperature interacting Bose gas is superfluidity. First observed in liquid 4He, this phenomenon has been intensively studied in a…
