Squeezed displaced fock states and non-diagonalPrepresentation
A.‐S. F. Obada, G. M. Abd Al-Kader · Journal of Modern Optics · 1998
An R representation with a squeezed displaced-Fock-states (SDFSs) basis is introduced. A non-diagonal P representation for the density operator with SDFS basis is defined. The special cases for the fields, chaotic and laser, are calculated. The Pegg–Barnett phase distribution is given and compared with the radial integration of the generalized P function. The Fokker–Planck equation for the damped harmonic oscillator is considered, and its steady-state solution is given.
