Abstract

Based on the property of Wigner function，we use quantum mechanics to deal with damped system. The Wigner function of the damped harmonic oscillator in non-commutative phase space is obtained by considering the non-commutative of the coordinate-coordinate and momenta-momenta in the relation of space variable.

Key words： damped systems; non-commutative phase space ( NCPS); Wigner function
