Solution of the quantum liouville equation as a stochastic process

The equation of motion of the density operator in the Wigner representation is related to a generalized stochastic process which can be simulated by computer. This leads to a practical method for computing the time evolution of large quantum mechanical systems for which no other comparable method is...

Description
Summary:The equation of motion of the density operator in the Wigner representation is related to a generalized stochastic process which can be simulated by computer. This leads to a practical method for computing the time evolution of large quantum mechanical systems for which no other comparable method is currently available.
