The effective potential and resummation procedure to multidimensional complex cubic potentials for weak and strong-coupling
arXiv:0705.2571 · doi:10.1063/1.2760354
Abstract
The method for the recursive calculation of the effective potential is applied successfully in case of weak coupling limit (g tend to zero) to a multidimensional complex cubic potential. In strong-coupling limit (g tend to infinity), the result is resumed using the variational perturbation theory (VPT). It is found that the convergence of VPT-results approaches those expected.
