Topological susceptibility of pure gauge theory using Density of States

Understand

The topological susceptibility of the SU(3) pure gauge theory is calculated in the deconfined phase at temperatures up to $10T_c$.

• 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.
