Eigenvalues of the QCD Dirac operator at finite temperature and density
Elmar Bittner, Maria-Paola Lombardo, Harald Markum +1
We investigate the eigenvalue spectrum of the staggered Dirac matrix in two-color QCD at nonzero temperature and at baryon density when the eigenvalues become complex. The quasi-ze…

Universality and Chaos in Quantum Field Theories
B. A. Berg, E. Bittner, M. -P. Lombardo +3
We investigate the eigenvalue spectrum of the staggered Dirac matrix in SU(3) gauge theory and in full QCD as well as in quenched U(1) theory on various lattice sizes. As a measure…
