Modelling the Quark Determinant in Full QCD Simulations
A. Duncan, E. Eichten, H. Thacker
Abstract
The computational requirements and dynamics of Monte Carlo simulations of unquenched QCD incorporating the infrared quark eigenmodes (up to ≈ ΛQCD) exactly and UV modes via a loop representation are discussed. The accuracy of such a loop representation is studied for a variety of lattice volumes and quark masses. The method has been successfully applied for lattices up to 103x20 at a 0.17F with improved (clover) action, and allows simulations at or near kappa critical.
