A phenomenological universal expression for the condensate fraction in strongly-correlated two-dimensional Bose gases
G. E. Astrakharchik, I. L. Kurbakov, N. A. Asriyan +1
We investigate the relation between non-local and energetic properties in two-dimensional quantum systems of zero-temperature bosons. By analyzing numerous interaction potentials a…
Phase alignment in a lattice of exciton-polaritonic Bose-Einstein condensates
N. V. Kuznetsova, D. V. Makarov, N. A. Asriyan +1
Dynamics of exciton-polariton Bose-Einstein condensate is examined by means of the stochastic Gross-Pitaevskii equation including non-Markovian coupling to the excitonic reservoir.…
Bose-Einstein condensation of THz photons in an optical microcavity with Landau-quantized electrons
Timofey V. Maximov, Norayr A. Asriyan, Igor L. Kurbakov +1
We present a theoretical model for a coherent terahertz radiation source based on Bose-Einstein condensate of incoherently pumped microcavity photons. Energy relaxation is provided…
Stochastic model for assesing coherent properties of polariton condensates
N. A. Asriyan, A. A. Elistratov, Yu. E. Lozovik
By considering a microscopical model, we derive an evolution equation for single-mode polariton condensate taking into account the fluctuations of the order parameter. We use it to…
Finite-size effects in two-photon correlations of exciton Bose-Einstein condensates
R. D. Ivanovskikh, I. L. Kurbakov, N. A. Asriyan +1
Accessing two-photon statistics via Hunbary Brown and Twiss (HBT)-type measurements is essential for investigations of excitonic Bose-condensates. In this paper we make use of quan…
Non-Markovian stochastic Gross-Pitaevskii equation for the exciton-polariton Bose-Einstein condensate
A. D. Alliluev, D. V. Makarov, N. A. Asriyan +2
In this paper, a non-Markovian Gross-Pitaevskii equation is proposed to describe the formation of a condensate in an exciton-polariton system under incoherent pumping. By introduci…
Mean field study of 2D quasiparticle condensate formation in presence of strong decay
N. A. Asriyan, A. A. Elistratov, Yu. E. Lozovik
Bose-condensation in a system of 2D quasiparticles is considered in the scope of a microscopic model. Mean-field dynamical equations are derived with the help of the Schwinger-Keld…
Optical probing in a bilayer dark-bright condensate system
N. A. Asriyan, I. L. Kurbakov, A. K. Fedorov +1
We consider a bilayer system of two-dimensional Bose-Einstein-condensed dipolar dark excitons (upper layer) and bright ones (bottom layer). We demonstrate that the interlayer inter…
