A new approach for scenario generation in Risk management
Juan-Pablo Ortega, Rainer Pullirsch, Josef Teichmann +1
We provide a new dynamic approach to scenario generation for the purposes of risk management in the banking industry. We connect ideas from conventional techniques -- like historic…
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…
Density profiles of small Dirac operator eigenvalues for two color QCD at nonzero chemical potential compared to matrix models
Gernot Akemann, Elmar Bittner, Maria-Paola Lombardo +2
We investigate the eigenvalue spectrum of the staggered Dirac matrix in two color QCD at finite chemical potential. The profiles of complex eigenvalues close to the origin are comp…
Quantum chaos in supersymmetric QCD at finite density
Elmar Bittner, Simon Hands, Harald Markum +1
We investigate the distribution of the spacings of adjacent eigenvalues of the lattice Dirac operator. At zero chemical potential , the nearest-neighbor spacing distribution $P(…
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…
