Superfluids are inviscid flows in which vorticity is supported on filaments with quantized circulation. Such objects, known as quantum vortices, exhibit a hydrodynamical behavior. Experimentally, the dynamics of superfluids has been studied by using

International audience; Turbulence in superfluid helium is unusual and presents a challenge to fluid dynamicists because it consists of two coupled, inter penetrating turbulent fluids: the first is inviscid with quantised vorticity, the second is vis

Microscopic structure and Dynamics of Vortices in a dense Superfluid

Autor: Villerot, Sophie

Vortices study's justification lays in the fact that those former play an important part in quantum turbulence. The Gross-Pitaevskii equation can't be a proper model for superfluid helium, but we can still use it to determine the order parameter of a

Exciton polaritons are half-light half-matter quasi-particles which have been the subject of very exciting studies in recent years. They are given by the strong coupling between excitonic transitions in semiconductors and the electromagnetic field co
