Comment on "Chiral symmetry restoration, the eigenvalue density of the Dirac operator, and the axial U(1) anomaly at finite temperature"
Matteo Giordano
Aoki, Fukaya, and Taniguchi claim that both the spectral density of the Dirac operator at the origin and the topological susceptibility must vanish identically for sufficiently sma…
Dirac spectrum in the chirally symmetric phase of a gauge theory. II
Matteo Giordano
I discuss the consequences of the constraints imposed on the Dirac spectrum by the restoration of chiral symmetry in the chiral limit of gauge theories with two light fermion flavo…
Dirac spectrum in the chirally symmetric phase of a gauge theory. I
Matteo Giordano
I study the consequences of chiral symmetry restoration for the Dirac spectrum in finite-temperature gauge theories in the two-flavor chiral limit, using Ginsparg--Wilson fermions…
Localization in the Dirac spectrum and gauge-field topology
Claudio Bonanno, Matteo Giordano
We study localization of the low Dirac modes in 3+1 dimensional pure gauge theory at zero and nonzero imaginary angle, with the aim of better characterizing t…
Center vortices and localized Dirac modes in the deconfined phase of (2+1)-dimensional lattice gauge theory
György Baranka, Dénes Berta, Matteo Giordano
We study the deconfinement transition in (2+1)-dimensional lattice gauge theory both as a percolation transition of center vortices and as a localization transition…
Localization of Dirac modes in a finite temperature SU(2) Higgs model
György Baranka, Matteo Giordano
Low-lying Dirac modes become localized at the finite-temperature transition in QCD and other gauge theories, indicating a strong connection between localization and deconfinement.…
