Fixed point action and topological charge for SU(2) gauge theory
Thomas A. DeGrand, Anna Hasenfratz, Decai Zhu
We present a theoretically consistent definition of the topological charge operator based on renormalization group arguments. Results of the measurement of the topological suscepti…

Scaling and Topological Charge of a Fixed Point Action for Gauge Theory
Thomas DeGrand, Anna Hasenfratz, Decai Zhu
We construct a few parameter approximate fixed point action for SU(2) pure gauge theory and subject it to scaling tests, via Monte Carlo simulation. We measure the critical couplin…

Instantons and Fixed Point Actions in SU(2) Gauge Theory
Thomas DeGrand, Anna Hasenfratz, Decai Zhu
We describe the properties of instantons in lattice gauge theory when the action is a fixed point action of some renormalization group transformation. We present a theoretically co…
