Dirac and Gor'kov spectra in two color QCD with chemical potential
Elmar Bittner, Maria-Paola Lombardo, Harald Markum +1
We analyze the eigenvalue spectrum of the staggered Dirac matrix in two-color QCD at nonzero baryon density when the eigenvalues become complex. The quasi-zero modes and their role…
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…
Quantum chaos and chiral symmetry at the QCD and QED phase transition
Elmar Bittner, Harald Markum, Rainer Pullirsch
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. As a measure of the fluctuation prope…
Spectrum of the U(1) staggered Dirac operator in four dimensions
B. A. Berg, H. Markum, R. Pullirsch +1
We compare the low-lying spectrum of the staggered Dirac operator in the confining phase of compact U(1) gauge theory on the lattice to predictions of chiral random matrix theory.…
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…
