作者计算了有限温度淬火规范理论去约束阶段中重叠狄拉克算子的低位谱。这表明存在手性凝聚体，他们通过直接随机估计证实了这一点。他们表明，造成手性凝聚态的光谱部分可以理解为源自瞬时子和反瞬时子的稀气体。
The authors compute the low lying spectrum of the overlap Dirac operator in the deconfined phase of finite-temperature quenched gauge theory. It suggests the existence of a chiral condensate which they confirm with a direct stochastic estimate. They show that the part of the spectrum responsible for the chiral condensate can be understood as arising from a dilute gas of instantons and anti-instantons.
