Fragmentation and the Bose-glass phase transition of the disordered 1D Bose gas
Luca Fontanesi, Michiel Wouters, Vincenzo Savona
We investigate the superfluid-insulator quantum phase transition in a disordered 1D Bose gas in the mean field limit, by studying the probability distribution of the density. The s…
Probing the Dynamics of Spontaneous Quantum Vortices in Polariton Superfluids
K. G. Lagoudakis, F. Manni, B. Pietka +6
The experimental investigation of spontaneously created vortices is of utmost importance for the understanding of quantum phase transitions towards a superfluid phase, especially f…
Energy Relaxation in a 1-D Polariton Condensate
M. Wouters, T. C. H. Liew, V. Savona
We study the kinetics of polariton condensation accounting for the condensation process as well as the energy relaxation of condensed polaritons due to their scattering with phonon…
Energy relaxation in the Gross-Pitaevskii equation
Michiel Wouters, Vincenzo Savona
We introduce a dissipation term in the Gross-Pitaevskii equation that describes the stimulated relaxation of condensed bosons due to scattering with a different type of particles.…
Coherent Oscillations in an Exciton-Polariton Josephson Junction
K. G. Lagoudakis, B. Pietka, M. Wouters +2
We report on the observation of spontaneous coherent oscillations in a microcavity polariton bosonic Josephson junction. The condensation of exciton polaritons takes place under in…
Are non-equilibrium Bose-Einstein condensates superfluid?
Michiel Wouters, Iacopo Carusotto
We theoretically study the superfluidity properties of a non-equilibrium Bose-Einstein condensate of exciton-polaritons in a semiconductor microcavity. The dynamics of the condensa…
