随机矩阵理论的最新进展使人们能够从价狄拉克算符的本征值对虚同位旋化学势的依赖性来确定赝标衰变常数。我们执行这个想法的试点测试,从模拟两种口味的动态重叠费米子。
Recent advances in random matrix theory enable one to determine the pseudoscalar decay constant from the dependence of the eigenvalues of the valence Dirac operator on an imaginary isospin chemical potential. We perform a pilot test of this idea, from simulations with two flavors of dynamical overlap fermions.
