Husimi Functions of Excited Squeezed Vacuum States

Meng Xiang-Guo, Ji‐Suo Wang, Liang Bao-Long

Based on the Husimi operator in pure state form introduced by Fan et al., which is a squeezed coherent state projector, and the technique of integration within an ordered product (IWOP) of operators, as well as the entangled state representations, we obtain the Husimi functions of the excited squeezed vacuum states (ESVS) and two marginal distributions of the Husimi functions of the ESVS.

Husimi operator and Husimi function for describing electron's probability distribution in uniform magnetic field derived by virtue of the entangled state representation

Hong-Yi Fan, Qin Guo

For the first time we introduce the Husimi operator Delta_h(gamma,varepsilon;kappa) for studying Husimi distribution in phase space(gamma,varepsilon) for electron's states in uniform magnetic field, where kappa is the Gaussian spatial width parameter. Using the Wigner operator in the entangled state |lambda> representation [Hong-Yi Fan, Phys. Lett. A 301 (2002)153; A 126 (1987) 145) we find that Delta_h(gamma,varepsilon;kappa) is just a pure squeezed coherent state density operator |gamma,varepsilon>_kappa kappaFor the first time we introduce the Husimi operator Delta_h(gamma,varepsilon;kappa) for studying Husimi distribution in phase space(gamma,varepsilon) for electron's states in uniform magnetic field, where kappa is the Gaussian spatial width parameter.

Generalized Husimi operator as the rotated and squeezed coherent state projector and its application

Ye‐Jun Xu, Wang Xian-cai, Gui Chuan-you +1 more

We propose a so-called generalized Husimi operator ?gh(x, p, ?, ?) corresponding to the generalized Husimi function and prove ?gh(x, p, ?, ?) = |x, p, ?, ???x, p, ?, ?|, i.e. ?gh(x, p, ?, ?) is actually a pure state projector. Further, |x, p, ?, ?? turns out to be a rotated and squeezed coherent state . As an application, we propose a measured scheme on the generalized Husimi function in the context of a single trapped ion.
