A pion decay constant in the multi-flavor Schwinger model
Jaime Fabián Nieto Castellanos, Ivan Hip, Wolfgang Bietenholz
The pion decay constant plays an important role in QCD and in Chiral Perturbation Theory. It is hardly known, however, that a corresponding constant exists in the Schwinger m…
An analogue to the pion decay constant in the multi-flavor Schwinger model
Jaime Fabián Nieto Castellanos, Ivan Hip, Wolfgang Bietenholz
We study the Schwinger model with degenerate fermion flavors, by means of lattice simulations. We use dynamical Wilson fermions for , and re-weigh…
New insight in the 2-flavor Schwinger model based on lattice simulations
Jaime Fabián Nieto Castellanos, Wolfgang Bietenholz, Ivan Hip
We consider the Schwinger model with two degenerate, light fermion flavors by means of lattice simulations. At finite temperature, we probe the viability of a bosonization method b…
Finite temperature and delta-regime in the 2-flavor Schwinger model
Ivan Hip, Jaime Fabián Nieto Castellanos, Wolfgang Bietenholz
The Schwinger model is often used as a testbed for conceptual and numerical approaches in lattice field theory. Still, some of its rich physical properties in anisotropic volumes h…
Microscopic Dirac Spectrum in a 2d Gauge Theory with Zero Chiral Condensate
Wolfgang Bietenholz, Ivan Hip, David Landa-Marbán
Fermionic theories with a vanishing chiral condensate (in the chiral limit) have recently attracted considerable interest; in particular variants of multi-flavour QCD are candidate…
Features of a 2d Gauge Theory with Vanishing Chiral Condensate
David Landa-Marbán, Wolfgang Bietenholz, Ivan Hip
The Schwinger model with flavors is a simple example for a fermionic model with zero chiral condensate Sigma (in the chiral limit). We consider numerical data for two…
