Résumé

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 we 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.

Single-photon source

Single-photon sources are light sources that emit light as single particles or photons. These sources are distinct from coherent light sources (lasers) and thermal light sources such as incandescent light bulbs. The Heisenberg uncertainty principle dictates that a state with an exact number of photons of a single frequency cannot be created. However, Fock states (or number states) can be studied for a system where the electric field amplitude is distributed over a narrow bandwidth.

Generalized function

In mathematics, generalized functions are objects extending the notion of functions. There is more than one recognized theory, for example the theory of distributions. Generalized functions are especially useful in making discontinuous functions more like smooth functions, and describing discrete physical phenomena such as point charges. They are applied extensively, especially in physics and engineering. A common feature of some of the approaches is that they build on operator aspects of everyday, numerical functions.

Fonction de Green

En mathématiques et en physique, une fonction de Green est une solution (également appelée solution élémentaire ou solution fondamentale) d'une équation différentielle linéaire à coefficients constants, ou d'une équation aux dérivées partielles linéaire à coefficients constants. Ces « fonctions » de Green, qui se trouvent être le plus souvent des distributions, ont été introduites par George Green en 1828 pour les besoins de l'électromagnétisme. Le mémoire de Green restera confidentiel jusqu'à sa republication en trois parties, à partir de 1850.
