“…However, in some cases, it is quite realistic. It was successfully accomplished, for example, in [19]- [20] for the description of slowing and absorption processes of electromagnetic waves in gases of alkali metals with BEC or propagation of relativistic charged particles in the same substances [21]. These studies used a microscopic approach based on the low energy quantum electrodynamics, constructed in [24].…”

“…These studies used a microscopic approach based on the low energy quantum electrodynamics, constructed in [24]. There is a hope to generalize the approach of [24], [19]- [21] in order to calculate the effective mass of the photon in the systems similar to those considered in the present paper.…”

“…However, both the derivation of dispersion equations for specific mediums, and their solutions are separated problems, and solving each of them involves considerable mathematical difficulties. Such difficulties, that rise while deriving and solving the dispersion equations for electromagnetic waves in the systems with bound states and in the presence of a Bose condensate, can be estimated from works [18]- [21]. Therefore, in this paper we shall not intend to determine the cut-off frequency of the photon spectrum and their velocities in the present system, considering them to be given.…”

We study peculiarities of Bose-Einstein condensation of photons that are in thermodynamic equilibrium with atoms of noninteracting gases. General equations of the thermodynamic equilibrium of the system under study are obtained. We examine solutions of these equations in the case of high temperatures, when the atomic components of the system can be considered as nondegenerated ideal gases of atoms, and the photonic component can form a state with the Bose condensate. Transcendental equation for transition temperature and expression for the density of condensed photons in the considered system are derived. We also obtain analytical solutions of the equation for the critical temperature in a number of particular cases. The existence of two regimes of Bose condensation of photons, which differ significantly in nature of transition temperature dependence on the total density of photons pumped into the system, is revealed. In one case, this dependence is a traditional fractional-power law, and in another one it is the logarithmic law. Applying numerical methods, we determine boundaries of existence and implementation conditions for different regimes of condensation depending on the physical parameters of the system under study. We also show that for a large range of physical systems that are in equilibrium with photons (from ultracold gases of alkali metals to certain types of ideal plasma), the condensation of photons should occur according to the logarithmic regime.Comment: 12 pages, 3 figure

We study theoretically a gas consisting of charged bosons (ions) over the flat dielectric surface at low temperatures and its tendency to form a state with a Bose-Einstein condensate. For the stability of a system, an additional external electric field, which keeps charges at the dielectric surface, is introduced. The formalism is developed in the framework of a self-consistent-field approach, which combines the quasiclassical description in terms of the Wigner distribution functions and the quantum-mechanical approach by employing the Gross-Pitaevskii equation. We predict a formation of the state with a Bose-Einstein condensate and determine the near-critical physical characteristics of the system. It is shown that the thermal and condensate components become spatially separated under these conditions.

“…Studies [7,8] predicted the capability of controlling the group velocity of light in gases with BEC using an external magnetic field [12] as well as the possibility of using BEC for filtering optical electromagnetic signals [13]. Interesting effects [14,15] and the effects associated with the passage of charged particles through systems with BEC were predicted in [16].…”

We have studied conditions of photon Bose-Einstein condensate formation that is in thermodynamic equilibrium with ideal gas of two-level Bose atoms below the degeneracy temperature. Equations describing thermodynamic equilibrium in the system were formulated; critical temperatures and densities of photonic and atomic gas subsystems were obtained analytically. Coexistence conditions of these photonic and atomic Bose-Einstein condensates were found. There was predicted the possibility of an abrupt type of photon condensation in the presence of Bose condensate of ground-state atoms: it was shown that the slightest decrease of the temperature could cause a significant gathering of photons in the condensate. This case could be treated as a simple model of the situation known as "stopped light" in cold atomic gas. We also showed how population inversion of atomic levels can be created by lowering the temperature. The latter situation looks promising for light accumulation in atomic vapor at very low temperatures.
