Normally Ordered Form of Smoothed Wigner Operator and its Applications
Hong-Yi Fan, Guo-Liang Tong
Abstract
Using the IWOP (integration within ordered product) technique, we derive a normally ordered form of the smoothed Wigner operator with which the smoothed Wigner function, that is specified only in the integral form in the literature, can be simplified. The application of the new form of the smoothed Wigner operator to the coherent state is also presented.
