9 May 2001 Fokker-Planck equations for quantum amplifiers and squeezing
Author Affiliations +
The Fokker-Planck equations (FPE) which determine the time dependence of P -- symbol of the density matrix of quantum parametric amplifiers are derived and their group properties are investigated. Exploring the coherent states method, constructing the dynamical symmetry group of FPE and generalizing the well known Wei-Norman method to the case of FPE, we have found FPE solutions exactly. The initial squeezing influence of the thermal reservoir is discussed.
