Ob. Prepelitsa, QUANTUM-ELECTRODYNAMIC PROCESSES IN A STRONG NONCLASSICAL ELECTROMAGNETIC-FIELD, Journal of experimental and theoretical physics, 85(5), 1997, pp. 838-845
Quantum-electrodynamic processes that take place in the presence of a
squeezed electromagnetic field are discussed. Integral formulas are de
rived that make it possible to express the probability of any process
in a squeezed electromagnetic field in terms of the probability of the
same process in a classical electromagnetic field. The main laws that
govern processes of first order in the fine-structure constant as fun
ctions of the number of photons involved and the quantum fluctuations
are examined. Tunneling formulas for the probability of a photon produ
cing an electron-positron pair in a strong squeezed field are derived.
Also, resonant electron-electron scattering is examined and the scatt
ering cross section as a function of the statistical properties of the
field (the way the field has been squeezed) is investigated. It is fo
und that the quantum fluctuations of the squeezed electromagnetic fiel
d give rise to an increase in the scattering cross section, with the p
robability of the process in a phase-squeezed electromagnetic field al
ways being higher than the probability of the process in an amplitude-
squeezed electromagnetic field. (C) 1997 American Institute of Physics
