【 摘 要 】

In this paper, we show the existence of various types of non-classical effects in the model of the nonlinear Kerr-coupler containing two quantum nonlinear oscilators mutually coupled by continuous nonlinear interaction, such as squeezing, anti-bunching, intermodal entanglement and their higher-order counterparts. By using unitary evolution operator formalism and the common inequalities expressed in term of various moments defined by products of creation and annihilation operators, we find numerically the "exact" solutions of these factors for non-dissipative. We show and discuss the parameters considered can be indicators of generation such nonclassical effects and hence, quantumness of the system.
