Two-photon transport in a waveguide coupled to a cavity in a two-level system
Two-photon transport waveguide coupled cavity two-level system
font style='font-size:12px;'>
2015/8/10
We study two-photon effects for a cavity quantum electrodynamics system where a waveguide is coupled to a cavity embedded in a two-level system. The wave function of two-photon scattering is exactly s...
Few-photon transport in a waveguide coupled to a pair of colocated two-level atoms
Few-photon transport waveguide coupled colocated two-level atoms
font style='font-size:12px;'>
2015/8/7
We calculate the one- and two-photon scattering matrices of a pair of collocated nonidentical two-level atoms coupled to a waveguide. We show that by proper choice of a two-photon input, the backgroun...
