Generating entangled polaritonic condensates by pumping with entangled pairs of photons
N. A. Asriyan, A. A. Elistratov, A. V. Kavokin
We investigate the steady state of two single-mode uniform spatially separated polaritonic conden- sates exposed to resonant pumping with entangled pairs of photons. We demonstrate…
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…
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 2D quantum systems of zero-temperature bosons. By analyzing numerous interaction potentials across densiti…
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.…
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…
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…
