The massive Thirring / sine-Gordon model with non-zero current density
Eric Oevermann, Thomas D. Cohen
This paper determines the zero-temperature equation of state for the massive Thirring / sine-Gordon model. This demonstrates recently derived model-independent upper and lower boun…

Functional renormalization of QCD in dimensions: four-fermion interactions from quark-gluon dynamics
Eric Oevermann, Adrian Koenigstein, Stefan Floerchinger
Quantum Chromodynamics in two spacetime dimensions is investigated with the Functional Renormalization Group. We use a functional formulation with covariant gauge fixing and derive…
