用态密度研究纯规范理论的拓扑磁化率

Topological susceptibility of pure gauge theory using Density of States

Szablocs Borsanyi, Dénes Sexty

摘要:

本文计算了SU(3)纯规范理论在温度达到$10T_c$的退禁闭相的拓扑磁化率。在如此高的温度下,磁化率被抑制,拓扑非平凡的配置是极其罕见的。因此,直接晶格模拟是不可行的。设计了模拟稀有事件的态密度(DoS)方法,给出了它在高温拓扑敏感性问题中的应用。我们重建的直方图的收费部门,人们可以在一个天真的重要性抽样。我们的发现与自由瞬子气体完全一致。

英文摘要:

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. 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.
