Nonstationary quantum parametrical processes
This work deals with the spectral problems for multimode effective hamiltonians of quantum parametric processes. Also we investigate statistical properties of parametric radiation and improve photodetection protocols if its state.
Dynamical Casimir Effect is a relativistic process of photons creation out of vacuum due to the accelerated motion of the cavity mirrors or changing electromagnetic properties of intracavity media. We introduce the indirect measurement protocol for detection of Casimir field statistical properties.
