Quantum Chaos in Physical Systems: from Super Conductors to Quarks
Elmar Bittner, Harald Markum, Rainer Pullirsch
This article is the written version of a talk delivered at the Bexbach Colloquium of Science 2000 and starts with an introduction into quantum chaos and its relationship to classic…
Spins coupled to a -Regge lattice in 4d
Elmar Bittner, Wolfhard Janke, Harald Markum
We study an Ising spin system coupled to a fluctuating four-dimensional -Regge lattice and compare with the results of the four-dimensional Ising model on a regular lattice. P…
Lowest eigenvalues of the Dirac operator for two color QCD at finite density
Elmar Bittner, Maria-Paola Lombardo, Harald Markum +1
We investigate the eigenvalue spectrum of the staggered Dirac matrix in full QCD with two colors and finite chemical potential. Along the strong-coupling axis up to the temperature…
Lowest eigenvalues of the Dirac operator for two color QCD at nonzero chemical potential
Elmar Bittner, Maria-Paola Lombardo, Harald Markum +1
We investigate the eigenvalue spectrum of the staggered Dirac matrix in SU(3) and U(1) gauge theory as well as in full QCD with two colors and finite chemical potential. Along the…
