Atom-field transfer of coherence in a two-photon micromaser assisted by a classical field
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 (entropy close to zero) due to its interaction with atoms sent across the cavity. We trace over the atomic variables, i.e., the atomic states ...

متن کاملCollective Two-Atom Effects and Trapping States in the Micromaser
We investigate signals of trapping states in the micromaser system in terms of the average number 〈n〉 of cavity photons as well as a suitably defined correlation length of atoms leaving the cavity. In the description of collective two-atom effects we allow the mean number, ǫ, of pump atoms inside the cavity during the characteristic atomic cavity transit time to be as large as of order one. The...
متن کاملDetuning effects in the vertical cold-atom micromaser
Abstract. The quantum theory of the cold atom micromaser including the effects of gravity is established in the general case where the cavity mode and the atomic transition frequencies are detuned. We show that atoms which classically would not reach the interaction region are able to emit a photon inside the cavity. The system turns out to be extremely sensitive to the detuning and in particul...
متن کاملInformation Transfer through Classifiers
We have previously proposed the use of quadratic Renyi’s mutual information, estimated using Parzen windowing, as an ICA criterion and showed that it utilizes data more efficiently than classical algorithms like InfoMax and FastICA. We suggested the use of Renyi’s definition of information theoretic quantities rather than Shannon’s definitions since the Shannon’s definitions are already include...
