چکیده

The spectral flow of the low-lying eigenvalues of the improved and unimproved Wilson-Dirac operator is studied on instanton-like configurations and on thermalized quenched configurations at various β-values and lattice sizes. We also investigate the space-time localisation and chirality of the corresponding eigenvectors.

Spectral properties of the Wilson Dirac operator in the -regime

We investigate the spectral properties of the Wilson Dirac operator in quenched QCD in the microscopic regime. We distinguish the topological sectors using the index as determined by the Wilson flow method. Consequently, the distributions of the low-lying eigenvalues of the Wilson Dirac operator can be compared in each of the topological sectors to predictions from random matrix theory applied ...

Acceleration of the Arnoldi method and real eigenvalues of the non-Hermitian Wilson-Dirac operator

In this paper, we present a method for the computation of the low-lying real eigenvalues of the Wilson-Dirac operator based on the Arnoldi algorithm. These eigenvalues contain information about several observables. We used them to calculate the sign of the fermion determinant in oneflavor QCD and the sign of the Pfaffian in N = 1 super Yang-Mills theory. The method is based on polynomial transf...

Cutoff–effects in the spectrum of dynamical Wilson fermions

We investigate the low–lying eigenvalues of the improved Wilson–Dirac operator in the Schrödinger functional with two dynamical quark flavors. At a lattice spacing of approximately 0.1 fm we find more very small eigenvalues than in the quenched case. These cause problems with HMC–type algorithms and in the evaluation of fermionic correlation functions. Through a simulation at a finer lattice sp...

An exploratory study of the low-lying eigenvalues of the Wilson-Dirac operator and their corresponding eigen-vectors is presented. Results for the eigenvalues from quenched and unquenched simulations are discussed. The eigenvectors are studied with respect to their localization properties in the quenched approximation for the cases of SU(2) and SU(3).

Low-lying Eigenvalues of the QCD Dirac Operator at Finite Temperature

We compute the low-lying spectrum of the staggered Dirac operator above and below the finite temperature phase transition in both quenched QCD and in dynamical four flavor QCD. In both cases we find, in the high temperature phase, a density with close to square root behavior, ρ(λ) ∼ (λ − λ0) . In the quenched simulations we find, in addition, a volume independent tail of small eigenvalues exten...
