Topological susceptibility of pure gauge theory using Density of States
The topological susceptibility of the SU(3) pure gauge theory is calculated
in the deconfined phase at temperatures up to . At such large
temperatures the susceptibility is suppressed, topologically non-trivial
configurations are extremely rare. Thus, direct lattice simulations are not
feasible. The density of states (DoS) method is designed to simulate rare
events, we present an application of the DoS method to the problem of high
temperature topological susceptibility. We reconstruct the histogram of the
charge sectors that one could have obtained in a naive importance sampling. Our
findings are perfectly consistent with a free instanton gas.Comment: 10 pages, 6 figures, PLB versio
