Constraints on the Dirac spectrum from chiral symmetry restoration and the fate of $U (1)_{A}$ symmetry

Matteo Giordano

I discuss chiral symmetry restoration in the chiral limit $m \to 0$ of QCD with two light quark flavours of mass $m$ , focussing on its consequences for scalar and pseudoscalar susce…

Center vortices and localized Dirac modes in the deconfined phase of (2+1)-dimensional lattice $Z_{2}$ gauge theory

György Baranka, Dénes Berta, Matteo Giordano

We study the deconfinement transition in (2+1)-dimensional lattice $Z_{2}$ gauge theory both as a percolation transition of center vortices and as a localization transition…

Phase diagram of a generalized Stephanov model for finite-density QCD

György Baranka, Matteo Giordano

We solve a random matrix model for QCD at finite chemical potential, obtained by generalizing the Stephanov model by modifying the random-matrix integration measure with a one-para…

Constraints on the Dirac spectrum from chiral symmetry restoration

Matteo Giordano

I derive constraints on the Dirac spectrum in the chirally symmetric phase of a gauge theory with two massless fermion flavors. Using only general properties of correlation functio…
