Beyond the Thouless energy
M. E. Berbenni-Bitsch, M. Göckeler, H. Hehl +4
The distribution and the correlations of the small eigenvalues of the Dirac operator are described by random matrix theory (RMT) up to the Thouless energy ,…
Random Matrix Theory, Chiral Perturbation Theory, and Lattice Data
M. E. Berbenni-Bitsch, M. Göckeler, H. Hehl +4
Recently, the chiral logarithms predicted by quenched chiral perturbation theory have been extracted from lattice calculations of hadron masses. We argue that the deviations of lat…
Random Matrix Theory and Chiral Logarithms
M. E. Berbenni-Bitsch, M. Göckeler, H. Hehl +4
Recently, the contributions of chiral logarithms predicted by quenched chiral perturbation theory have been extracted from lattice calculations of hadron masses. We argue that a de…
Universal and non-universal behavior in Dirac spectra
M. E. Berbenni-Bitsch, M. Göckeler, S. Meyer +2
We have computed ensembles of complete spectra of the staggered Dirac operator using four-dimensional SU(2) gauge fields, both in the quenched approximation and with dynamical ferm…
Microscopic universality with dynamical fermions
M. E. Berbenni-Bitsch, S. Meyer, T. Wettig
It has recently been demonstrated in quenched lattice simulations that the distribution of the low-lying eigenvalues of the QCD Dirac operator is universal and described by random-…
Random-matrix universality in the small-eigenvalue spectrum of the lattice Dirac operator
M. E. Berbenni-Bitsch, A. D. Jackson, S. Meyer +3
We analyze complete spectra of the lattice Dirac operator in SU(2) gauge theory and demonstrate that the distribution of low-lying eigenvalues is described by random matrix theory.…
