The Wigner functions of neutral particles with structure in an external electromagnetic field
Wang Jian-hua
The Wigner functions play a significant role in quantum mechanics,quantum optics,thermodynamics and quantum statistics.Therefore,it has high research value to investigate the Wigner functions for neutral particles with structure that moving in an external electromagnetic field.In this paper,first,we introduce the properties and application of Wigner function.Then,we provide the Hamiltonian of the polarized atom using the symmetric gauge.At last,by using Bopp shift,we solve the energy eigenvalue equation with the Moyal-Weyl star product,and obtain the energy levels and Wigner functions of the neutral particles in an external electromagnetic field.
