A Study about Single-Photon Transport Controlled by Dipole-Dipole Interaction in a One-Dimensional Coupled Waveguide Cavity

Abstract

In this paper, by regulating the dipole-dipole interaction between atoms, we can successfully control the behavior of single-photon transport in one-dimensional waveguide cavity. Our findings indicate that the dipole-dipole interaction is equivalent to the positive detuning. Furthermore, we also found that there is a competition between dipole-dipole interaction and the atom-cavity coupling. In addition, we also studied the influences of dipole-dipole interaction on transport spectrum under extreme conditions of high and low energy.
