Exciton-Polariton Bose-Einstein Condensates

Exciton-polaritons, mixed light-matter quasiparticles in semiconductors, have recently shown evidence for Bose-Einstein condensation. Some of the properties of condensates of exciton-polaritons are reviewed in this article. We first discuss the spontaneous ...

Elementary Excitations of Superfluid Helium Droplets Probed by Ion Spectroscopy

Marcel Drabbels, Xiaohang Zhang

Electronic spectra of molecules in helium droplets reveal spectral features that are related to the elementary excitations of the superfluid helium environment. In order to determine to what extend the interaction strength of the molecule with the helium a ...

Picosecond solvation dynamics of alkali cations in superfluid 4He nanodroplets

Marcel Drabbels, Alberto Hernando de Castro

The dynamics following the photoionization of neutral Rb and Cs atoms residing in a dimple at the surface of a superfluid 4He1000 nanodroplet has been investigated within time-dependent density functional theory, complementing a previous study on Ba. The c ...

Critical Landau velocity in helium nanodroplets

Marcel Drabbels, Evgeniy Loginov, Nils Benedict Brauer, Alberto Hernando de Castro

The best-known property of superfluid helium is the vanishing viscosity that objects experience while moving through the liquid with speeds below the so-called critical Landau velocity. This critical velocity is generally considered a macroscopic property ...

Four-wave mixing excitations in a dissipative polariton quantum fluid

Benoît Marie Joseph Deveaud, Marcia Portella Oberli, Verena Kohnle

The Bogoliubov transformation of a polariton quantum fluid has recently been revealed in the four-wave mixing response of a driven microcavity polariton gas. In this work, we investigate the modifications that the dual nature of microcavity polaritons prod ...

Dissociation dynamics of singly charged vortices into half-quantum vortex pairs

Benoît Marie Joseph Deveaud, Vincenzo Savona, Timothy Chi Hin Liew, Konstantinos Lagoudakis, Francesco Manni

The quest for identification and understanding of fractional vorticity is a major subject of research in the quantum fluids domain, ranging from superconductors, superfluid Helium-3 to cold atoms. In a two-dimensional Bose degenerate gas with a spin degree ...

Hydrodynamic nucleation of quantized vortex pairs in a polariton quantum fluid

Benoît Marie Joseph Deveaud, Gaël Nardin, Gabriele Grosso, François Morier-Genoud, Barbara Pietka

Quantized vortices appear in quantum gases at the breakdown of superfluidity. In liquid helium and cold atomic gases, they have been indentified as the quantum counterpart of turbulence in classical fluids. In the solid state, composite light-matter bosons ...

Soliton Instabilities and Vortex Street Formation in a Polariton Quantum Fluid

Benoît Marie Joseph Deveaud, Gaël Nardin, Gabriele Grosso, François Morier-Genoud

Exciton polaritons have been shown to be an optimal system in order to investigate the properties of bosonic quantum fluids. We report here on the observation of dark solitons in the wake of engineered circular obstacles and their decay into streets of qua ...
