Semiconductor microcavities offer unique systems in which to investigate the physics of
weakly interacting bosons. Their elementary excitations, polaritons—mixtures of excitons …

After the discovery of zero viscosity in liquid helium, other fundamental properties of the
superfluidity phenomenon have been revealed. One of them, irrotational flow, gives rise to …

Polaritons have a demonstrated impact on nanophotonic applications in the midinfrared
through visible spectral range. Surface phonon-polaritons (SPhPs) offer a way to bring the …

We investigate the question of 'why customary macroscopic entities appear to us humans as
they do, ie, as bounded entities occupying space and persisting through time', starting from …

We report on the formation of a diverse family of transverse spatial polygon patterns in a
microcavity polariton fluid under coherent driving by a blue-detuned pump. Patterns emerge …

We demonstrate room temperature lasing through the polaritonic mode of a J-aggregate
microcavity in which losses from exciton-exciton annihilation and slow polariton relaxation …

We demonstrate the existence of a cross Feshbach resonance by strongly driving a lower
polariton mode and by monitoring in time the transmission of a short optical pulse at the …

The fundamental mode of rotation in quantum fluids is given by a vortex whose quantized
value yields the orbital angular momentum (OAM) per particle. If the vortex is displaced (off …

We study analytically the dynamics of vortices in strongly coupled exciton-photon fields in
the presence of energy detuning. We derive equations for the vortex core velocity and mass …
