摘要：
The variational perturbation theory for quantum statistical density matrices is applied to complex cubic potentials such as: V(x, y) = x(2) + y(2) + ilambdaxy(2) and V(x, y, z) = x(2) + y(2) + z(2) + ilambdaxyz, where lambda is a real parameter. It is found that the energy spectra are real and positive. (C) 2004 Published by Elsevier B.V.
