Concurrence of Two Identical Atoms in a Rectangular Waveguide: Linear Approximation with Single Excitation
arXiv:1901.01795 · doi:10.1007/s11128-020-2577-y
Abstract
We study two two-level systems (TLSs) interacting with a reservoir of guided modes confined in a rectangular waveguide. For the energy separation of the identical TLSs far away from the cutoff frequencies of transverse modes, the delay-differential equations are obtained with single excitation initial in the TLSs. The effects of the inter-TLS distance on the time evolution of the concurrence of the TLSs are examined.
