Thermalization of a two-level atom in a planar dielectric system out of thermal equilibrium
Phys. Rev. A,2015,92(6):062503 | 2015年12月16日 | https://doi.org/10.1103/PhysRevA.92.062503
We study the thermalization of an elementary quantum system modeled by a two-level atom interacting with stationary electromagnetic fields out of thermal equilibrium near a dielectric slab. The slab is held at a temperature different from that of the region where the atom is located. We find that when the slab is nonabsorbing and nondispersive, out-of-thermal-equilibrium effects exist only when its thickness is infinite. In other words, no out-of-thermal-equilibrium effects appear for a real dielectric slab of a finite thickness d. Furthermore, a finite thick dielectric slab with a tiny imaginary part in the relative permittivity Imε behaves like a half-space dielectric substrate if Imε√Reε−1dλ0>1 is satisfied, where λ0 is the transition wavelength of the atom. This condition can serve as a guide for an experimental verification, using a dielectric substrate of a finite thickness, of the effects that arise from out-of-thermal-equilibrium fluctuations with a half-space (infinite thickness) dielectric.
