Abstract: | In this paper we describe a new two-mode system, which consists of Kerr-like medium and down conversion process, called the
Kerr-down conversion system. Under a certain condition we can obtain an exact solution of the dynamical
equations of motion. For this system we investigate different kinds of
quadrature squeezing, e.g., single-mode, two-mode and sum-squeezing. Also we
give a more general definition of the principal squeezing. We show that the
amounts of nonclassical effects produced by the Kerr-like and down-conversion processes separately are greater than those
obtained from the Kerr-down conversion system where both the processes are in competition. |
