On the phase structure of the micromaser system

[摘要] We investigate, in an exact manner, the phase structure of the micromaser system in terms of the physical parameters at hand, such as the atom cavity transit time, tau, the atom-photon frequency detuning, Delta omega, the number of thermal photons, nh and the probability, a, for a pump atom to be in its excited state. Phase diagrams are mapped out for various values of the physical parameters. Al. sufficiently large values of the detuning, we find a twinkling mode of the micromaser system. A correlation Length is used to study fluctuations close to the various phase transitions. (C) Published by Elsevier Science B.V.
