Atom-field transfer of coherence in a two-photon micromaser assisted by a classical field
, 2014 We investigate the transfer of coherence from atoms to a cavity field initially in a statistical mixture in a two-photon micromaser arrangement. The field is progressively modified from a maximum entropy state (thermal state) towards an almost pure state
