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…
Synchronized and Desynchronized Phases of Exciton-Polariton Condensates in the Presence of Disorder
A. Baas, K. G. Lagoudakis, M. Richard +3
Condensation of exciton-polaritons in semiconductor microcavities takes place despite in plane disorder. Below the critical density the inhomogeneity of the potential seen by the p…
Parametric polariton amplification in semiconductor microcavities
Gaëtan Messin, Jean-Philippe Karr, Augustin Baas +5
We present novel experimental results demonstrating the coherence properties of the nonlinear emission from semiconductor microcavities in the strong coupling regime, recently inte…
Quantum degeneracy of microcavity polaritons
Augustin Baas, Jean-Philippe Karr, Marco Romanelli +2
We investigate experimentally one of the main features of a quantum fluid constituted by exciton polaritons in a semiconductor microcavity, that is quantum degeneracy of a macrosco…
