Evaporation/Condensation of Ising Droplets
Andreas Nussbaumer, Elmar Bittner, Wolfhard Janke
Recently Biskup et al. [Europhys. Lett. 60 (2002) 21] studied the behaviour of d-dimensional finite-volume liquid-vapour systems at a fixed excess of particles above the ambie…
Two-colour Lattice QCD with dynamical fermions at non-zero density versus Matrix Models
Gernot Akemann, Elmar Bittner
We provide first evidence that Matrix Models describe the low lying complex Dirac eigenvalues in a theory with dynamical fermions at non-zero density. Lattice data for gauge group…
Discretization and Continuum Limit of Quantum Gravity on a Four-Dimensional Space-Time Lattice
E. Bittner, W. Janke, H. Markum
The Regge Calculus is a powerful method to approximate a continuous manifold by a simplicial lattice, keeping the connectivities of the underlying lattice fixed and taking the edge…
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…
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…
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…
