Abstract
We have discovered the abnormally strong influence of the magnetic field on the optical properties of an atomic ensemble confined in a waveguide. We demonstrate qualitative changes in the character of spontaneous emission and single-atom susceptibility. Based on the revealed effects, we propose a scheme of a true single-photon source. Furthermore, we propose the highly efficient optical gate using just one atom.
