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…

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…

Restriction of macroscopic structural superlubricity due to structure relaxation by the example of twisted graphene bilayer

Alexander S. Minkin, Irina V. Lebedeva, Andrey M. Popov +3

The effect of structure relaxation on the potential energy surface (PES) of interlayer interaction of twisted graphene bilayer is studied for a set of commensurate moiré systems u…

Photon Bose-Condensate as a Tunable Terahertz Laser Source without Inversion

Timofey V. Maximov, Igor V. Bondarev, Igor L. Kurbakov +1

We develop a theoretical model for a tunable coherent terahertz radiation source based on the long-lived Bose condensate of photons. In the device we propose, the original photon p…

Magnetic and electronic properties of 1D hybrid nanoobjects composed of alternating polycyclic hydrocarbon regions and double carbon chains

Irina V. Lebedeva, Sergey A. Vyrko, Alexander S. Sinitsa +5

It has been proposed recently that 1D hybrid nanoobjects consisting of alternating double carbon chains and polycyclic carbon regions can be obtained from graphene nanoribbons of a…

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…
