Higher-order non-classical properties of nonlinear charge coherent states

Abstract

In this paper, the higher-order squeezing and the higher-order anti-bunching in two-mode nonlinear charge coherent states are studied. The analytical expressions of the conditions for existing the higher-order squeezing and the higher-order anti-bunching are obtained. It is showed that these states exhibit all the higher-order squeezing and the higher-order anti-bunching behaviors. However, the higher-order anti-bunching may or may not exist depending on the parameters of these states.
