Abstract

The exact theory of generating the "entangled photons" by excited motionless two level atom in one-dimensional high finesse nanocavity with a single resonance linearly polarized mode, decaying at the rate Γ, is presented. We have investigated the evolution of resonance emission out of the macromolecule-like system "nanocavity with resonance mode and excited atom" in area 0≤ Γ≤ 0.2g , where g is a coupling constant for electro-dipolar interaction. We have revealed that the source of arising of the entangled photons at the outlet of nanocavity is disintegration of metastable interference superpositional field structure, ejected through the partly transparent mirror out of the cavity. This structure is produced by the self-consistent AC Stark effect, created by electrical fields of rotating atomic dipole and resonance mode. The field splits atomic levels and radiation transitions between them, producing in the nanocavity pairs of anti-phase (ω_a ± g)- photons. Since the rate of mode damping Γ << g these photons form in the cavity metastable interference superposional structure consisting of resonance mode carring wave with amplitude modulated with frequency 2g. The profiles of (ω_a ± g )- components have identical form exp(-t Γ)t Γ, with average lifetime in the cavity being estimated as 4ln Γ/Γ.
