Modelling the Quark Determinant in Full QCD Simulations
Abstract
The computational requirements and dynamics of Monte Carlo simulations of unquenched QCD incorporating the infrared quark eigenmodes (up to ≈ QCD) 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.
