The demon method is applied to determine the effective action on blocked SU(3) gauge configurations. First the method is tested on SU(3) gauge configurations with known couplings. It turns out that the method works well to determine couplings with good precision in rather short microcanonical updates. Next the method is implemented for a set of blocked SU(3) gauge configurations and we successfully determine an effective action in seven-dimensional coupling constant space.

Abstract We compute the proper real-time interaction potential between a static quark and antiquark in classical lattice gauge theory at finite temperature. Our central result is the determination of the screened real-part of this potential, and we reconfirm the presence of an imaginary part. The real part is intimately related to the back-reaction of the static sources onto the gauge fields, incorporated via Gauss’s law. Differences in the treatment of static sources in quantum and classical lattice gauge theory are discussed.
