Microscopic Dirac Spectrum in a 2d Gauge Theory with Zero Chiral Condensate
Microscopic Dirac Spectrum in a 2d Gauge Theory with Zero Chiral Condensate
Fermionic theories with a vanishing chiral condensate (in the chiral limit) have recently attracted considerable interest; in particular variants of multi-flavour QCD are candidates for this behaviour. Here we consider the 2-flavour Schwinger model as a simple theory with this property. Based on simulations with light dynamical overlap fermions, we …
