Quantum chaos in QCD and hadrons
Harald Markum, Willibald Plessas, Rainer Pullirsch +2
This article is the written version of a talk delivered at the Workshop on Nonlinear Dynamics and Fundamental Interactions in Tashkent and starts with an introduction into quantum…
Pion scattering on the lattice with chirally improved fermions
Christof Gattringer, Dieter Hierl, Rainer Pullirsch
We report preliminary results for the I=2 pion scattering length a_0, calculated with chirally improved fermions. After chiral extrapolation our results are in good agreement with…
Full Spectrum of Lyapunov Exponents in Gauge Field Theory
Tamas S. Biro, Harald Markum, Rainer Pullirsch
We analyze the Lyapunov exponents of U(1) gauge fields across the phase transition from the confinement to the Coulomb phase on the lattice which are initialized by quantum Monte C…
Monopoles and Lyapunov Exponents in U(1) Lattice Gauge Theory
Harald Markum, Rainer Pullirsch, Wolfgang Sakuler
U(1) gauge fields are decomposed into a monopole and photon part across the phase transition from the confinement to the Coulomb phase. We analyze the leading Lyapunov exponents of…
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…
