Generalized Filinov transformation of the semiclassical initial value representation
2001
Journal of Chemical Physics
An efficient method is proposed for the practical solution of the "sign" problem for integrals involved in the semiclassical initial value representation. It is based on a generalization of the conventional Filinov filtering procedure which has the ͑approximate͒ effect of incorporating complex initial conditions into the phase space average; it does this by including an explicit oscillatory term in the filtering function that partially cancels the oscillatory part of the original integrand.
