A new algorithm of Langevin simulation and its application to the SU(2) and SU(3) lattice gauge
Hideo Nakajima, Sadataka Furui
Abstract
The 2nd order Runge-Kutta scheme Langevin simulation of unquenched QCD in pseudofermion method derived from our general theory shows a behaviour as a function of the Langevin step t better than the Fukugita,Oyanagi,Ukawa's scheme.
