Wehrl entropy and Wehrl phase distribution of a single-trapped ion interacting with a laser field

摘要

In this paper, some properties of the interaction between a single-trapped ion and laser fieldsare discussed. Analytical and explicit expressions of the Wehrl entropy and Wehrl phasedistribution are given taking into account different configurations of the laser field. The resultsshow the important roles played by the fluctuations of the laser phase and initial state settingin the evolution of the Husimi Q-function, Wehrl entropy and Wehrl phase distribution.
