A New Exact Method for Dynamical Fermion Computations with Non-Local Actions
Ivan Horvath, A. D. Kennedy, Stefan Sint
Abstract
We introduce a new algorithm which we call the Rational Hybrid Monte Carlo Algorithm (RHMC). This method uses a rational approximation to the fermionic kernel together with a noisy Kennedy-Kuti acceptance step to give an efficient algorithm with no molecular dynamics integration step-size errors.
