Squeezing property

In this paper, we study some non-classical properties and propose the generation schemes of the superposition of multiple-photon-added two-mode squeezed vacuum state (SMPA-TMSVS). Based on the Wigner function, we clarify that this state is a non-Gaussian state, while the original twomode squeezed vacuum state (TMSVS) is a Gaussian state.

In this paper, we study some higher-order nonclassical properties of the superposition of three-mode photon-added trio coherent states such as antibunching, squeezing, and entanglement. The results show that, for a fixed order, when the number of added photons is increased, the three-mode sum squeezing is more obvious, but the degrees of antibunching and three-mode entanglement are less manifested.

We consider the initial boundary value problem for 2D g-Navier-Stokes equations in bounded domains with homogeneous Dirichlet boundary conditions. We prove some important properties of solutions to the problem including the backward uniqueness property, the squeezing property.

This paper studies the higher-order nonclassical and entanglement properties in the photonadded trio coherent state (PATCS). We use the criterion of higher-order single-mode antibunching to evaluate the role of the photon addition operation. Furthermore, the general criteria for detection of higher-order three-mode sum squeezing and entanglement features in the PATCS are also investigated.

In this paper, we present the techniques of simulation modelling for quantum dynamics of Kerr nonlinear coupler system which consists of two nonlinear quantum oscillators mutually coupled by continuous nonlinear interaction. We show that by using evolution operator formalism we can model the quantum system and derive the “exact” solution for finding the existence of nonclassical properties in terms of squeezing, antibunching, intermodal entanglement and their higher order counterparts under the effect of dissipation process.

Squeezing properties of the Hillery-type N-powered amplitude are investigated in the linear and nonlinear fan-state. For a given k, squeezing may appear to the even power N = 2k and the number of directions along which the Nth-powered amplitude is squeezed is exactly equal to N, in both linear (the light field) and nonlinear (the vibrational motion of the trapped ion) fan-states.

We study the nonclassical properties of single-photon-added two-mode SU(1,1) coherent states. We derive the analytic expressions of the sum squeezing, the difference squeezing, the higher-order squeezing, the higher-order antibunching and the violation of the Cauchy– Schwarz inequality.
