Yang-Lee zeros of a random matrix model for QCD at finite density
M. A. Halasz, A. D. Jackson, J. J. M. Verbaarschot
We study the Yang-Lee zeros of a random matrix partition function with the global symmetries of the QCD partition function. We consider both zeros in the complex chemical potential…
Universal correlations in spectra of the lattice QCD Dirac operator
M. A. Halasz, T. Kalkreuter, J. J. M. Verbaarschot
Recently, Kalkreuter obtained complete Dirac spectra for lattice gauge theory both for staggered fermions and for Wilson fermions. The lattice size was as large as .…
On the spectrum of the QCD Dirac operator
J. J. M. Verbaarschot
In this lecture we argue that the fluctuations of Dirac eigenvalues on the finest scale, i.e. on the scale of the average level spacing do not depend on the underlying dynamics and…
Finite volume partition functions and Itzykson-Zuber integrals
A. D. Jackson, M. K. Şener, J. J. M. Verbaarschot
We find the finite volume QCD partition function for arbitrary quark masses. This is a generalization of a result obtained by Leutwyler and Smilga for equal quark masses. Our resul…
