Abstract

We report the calculation of cavity exciton-polariton phase diagram including realistic structural disorder. With increasing density polaritons first undergo a quasiphase transition toward a Bose glass: the condensate is localized in at least one minimum of the disorder potential. A further increase of the density leads to a percolation process of the polariton fluid giving rise to a Kosterlitz-Thouless phase transition toward superfluidity. The spatial representation of the condensate wave function as well as the spectrum of elementary excitations are obtained from the Gross-Pitaevskii equation for all the phases.

Theory of Bose-Einstein condensation and superfluidity of two-dimensional polaritons in an in-plane harmonic potential

Journal Article Berman, Oleg L ; Lozovik, Yurii E ; Snoke, David W - Physical Review. B, Condensed Matter and Materials Physics

Recent experiments have shown that it is possible to create an in-plane harmonic potential trap for a two-dimensional (2D) gas of exciton polaritons in a microcavity structure, and evidence has been reported of Bose-Einstein condensation of polaritons accumulated in this type of trap. We present here the theory of Bose-Einstein condensation (BEC) and superfluidity of the exciton polaritons in a harmonic potential trap. Along the way, we determine a general method for defining the superfluid fraction in a 2D trap, in terms of angular momentum representation. We show that in the continuum limit, as the trap becomes shallower, the superfluidmore »« less

Probing the Dynamics of Spontaneous Quantum Vortices in Polariton Superfluids

Journal Article Lagoudakis, K G ; Manni, F ; Pietka, B ; ... - Physical Review Letters

The experimental investigation of spontaneously created vortices is of utmost importance for the understanding of quantum phase transitions towards a superfluid phase, especially for two-dimensional systems that are expected to be governed by the Berezinski-Kosterlitz-Thouless physics. By means of time-resolved near-field interferometry we track the path of such vortices, created at random locations in an exciton-polariton condensate under pulsed nonresonant excitation, to their final pinning positions imposed by the stationary disorder. We formulate a theoretical model that successfully reproduces the experimental observations.

Cavity Exciton-Polaritons, Bose Einstein Condensation and Spin Dynamics

Journal Article Malpuech, Guillaume ; Solnyshkov, Dmitry ; Shelykh, Ivan ; ... - AIP Conference Proceedings

An introduction giving elementary properties of cavity exciton-polariton will be given. The condition of occurrence of the polariton lasing effect and of the polariton Bose Eintein condensation will be discussed. The impact of the structural disorder on the superfluid behavior of polariton condensates will be analysed. The spin properties of polariton condensates will be discussed. I will show how the anisotropy of the polariton-polariton interaction leads to the suppression of zeeman splitting for polariton condensates (spin Meissner effects). I will show how the combined impact of disorder and spin Meissner effect can lead to the formation of a new condensemore »« less

Superfluidity and Critical Velocities in Nonequilibrium Bose-Einstein Condensates

Journal Article Wouters, Michiel ; Carusotto, Iacopo - Physical Review Letters

We theoretically study the superfluidity properties of a nonequilibrium Bose-Einstein condensate of exciton polaritons in a semiconductor microcavity under incoherent pumping. The dynamics of the condensate is described at mean-field level in terms of a generalized Gross-Pitaevskii equation. The drag force on a small moving object and the onset of fringes in the density profile are shown to have a sharp threshold as a function of the velocity; a generalized Landau criterion is developed to explain this behavior in terms of the dispersion of elementary excitations. Metastability of supercurrents in multiply-connected geometries is shown to persist up to higher flowmore » speeds.« less

Bose-Einstein condensation and superfluidity of magnetoexcitons in bilayer graphene

Journal Article Berman, Oleg L ; Lozovik, Yurii E ; Gumbs, Godfrey - Physical Review. B, Condensed Matter and Materials Physics

We propose experiments to observe Bose-Einstein condensation and superfluidity of quasi-two-dimensional spatially indirect magnetoexcitons in two-layer graphene. The energy spectrum of collective excitations, the sound spectrum, and the effective magnetic mass of magnetoexcitons are presented in the strong magnetic field regime. The superfluid density n{sub S} and the temperature of the Kosterlitz-Thouless phase transition T{sub c} are shown to be increasing functions of the excitonic density n but decreasing functions of B and the interlayer separation D.
