Polariton Condensation in a One-Dimensional Disordered Potential
F. Manni, K. G. Lagoudakis, B. Pietka +5
We study the coherence and density modulation of a non-equilibrium exciton-polariton condensate in a one-dimensional valley with disorder. By means of interferometric measurements…
Competition between the Fulde-Ferrell-Larkin-Ovchinnikov phase and the BCS phase in the presence of an optical potential
Jeroen P. A. Devreese, Michiel Wouters, Jacques Tempere
In three dimensional Fermi gases with spin imbalance, a competition exists between Cooper pairing with zero and with finite momentum. The latter gives rise to the Fulde-Ferrell-Lar…
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…
Creation and detection of vortices in polariton condensates
Michiel Wouters, Vincenzo Savona
We investigate theoretically the creation, persistence and detection of quantized vortices in nonequilibrium polariton condensates within a stochastic classical field model. The li…
Superfluid to Bose-glass transition in a 1D weakly interacting Bose gas
Luca Fontanesi, Michiel Wouters, Vincenzo Savona
We study the one-dimensional Bose gas in spatially correlated disorder at zero temperature, using an extended density-phase Bogoliubov method. We analyze in particular the decay of…
