11.04.2016 - My new single-author paper on one-dimensional condensates of photons was published in Physical Review A.
This paper introduces a quasiequilibrium one-dimensional Bose-Einstein condensation of photons trapped in a microtube.
Light modes with a cutoff frequency (a photon's “mass”) interact through different processes of absorption, emission, and scattering on molecules and atoms.
In this paper I study the conditions for the one-dimensional condensation of light and the role of photon-photon interactions in the system.
The technique in use is the Matsubara Green's functions formalism modified for the quasiequilibrium system under study.
