STAGE OFFRE DE STAGE: VORTEX PAIR DYNAMICS IN SUPERFLUID OF LIGHT
Date de mise à jour de l’offre
laboratoire kastler brossel :
Le Laboratoire Kastler Brossel est un des acteurs majeurs dans le domaine de la physique quantique. Ses thématiques abordent de nombreux aspects depuis les tests fondamentaux de la théorie quantique jusqu’aux applications, couvrant ainsi une large gamme de sujets tels que les gaz quantiques, l’optique et l’information quantiques, les atomes et la lumière dans les milieux denses ou complexes, les tests des interactions fondamentales et la métrologie
Description de la mission
When light propagates in linear medium (vacuum, air etc), photon behaves as a noninteracting
gas, but when the medium is non-linear (an atomic vapor or a semiconductor
microcavity for examples), they start flowing as a liquid, called fluid of light. From the
medium, photons acquire an effective interaction that may lead to macroscopic coherent
behavior. Among the different system allowing to generate such particular fluids,
semiconductor microcavities are surely the more advanced, allowing for the observation of
superfluid of light [1,2] or of vortex pair appearing spontaneously when the superfluid flow
through a local potential barrier [3].
In the context of atomic superfluid the dynamics of these topological excitations are well
understood, but in the context of superfluid of light, the picture is blurred. This derives mainly
from the dissipative nature of fluids of light in cavities where the photon lifetime is so short
that the system needs to be continuously pumped. This driving dissipative scheme and its
interaction with vortex pair will be the focus of this internship. The student will investigate
numerically the dynamics of these pairs in presence of a coherent driving in realistic
experimental conditions.[1] A. Amo, J. Lefrère, S. Pigeon, C. Adrados, C. Ciuti, I. Carusotto, R. Houdré, E.
