چکیده انگلیسی
Considering the concept of “nonlinear coherent states”, we will study the interference effects by introducing the “superposition of two classes of nonlinear coherent states ” which are π2 out of phase. The formalism has then been applied to a few physical systems as “harmonious states”, “SU(1,1)SU(1,1) coherent states” and “the center of mass motion of trapped ion”. Finally, the nonclassical properties such as sub-Poissonian statistics, quadrature squeezing, amplitude-squared squeezing and Wigner distribution function of the superposed states have been investigated, numerically. Especially, as we will observe the Wigner functions of the superposed states take negative values in phase space, while their original components do not.
