Time Evolution of Relativistic Quantum Fields in Spatial Subregions
Markus Schröfl, Stefan Floerchinger
We study the time evolution of a state of a relativistic quantum field theory restricted to a spatial subregion . More precisely, we use the Feynman-Vernon influence functional…
Particle production and hadronization temperature in the massive Schwinger model
Laura Batini, Lara Kuhn, Jürgen Berges +1
We study the pair production, string breaking, and hadronization of a receding electron-positron pair using the bosonized version of the massive Schwinger model in quantum electrod…
Exact flow equation for the divergence functional
Stefan Floerchinger
An exact functional renormalization group flow equation is derived for the divergence functional which is a generalization of the Kullback-Leibler divergence to quantum field theor…
Information geometry of Euclidean quantum fields
Stefan Floerchinger
Information geometry provides differential geometric concepts like a Riemannian metric, connections and covariant derivatives on spaces of probability distributions. We discuss her…
Physical properties of the massive Schwinger model from the nonperturbative functional renormalization group
Patrick Jentsch, Romain Daviet, Nicolas Dupuis +1
We investigate the massive Schwinger model in dimensions using bosonization and the nonperturbative functional renormalization group. In agreement with previous studies we…
Conserved and non-conserved Noether currents from the quantum effective action
Stefan Floerchinger, Eduardo Grossi
The quantum effective action yields equations of motion and correlation functions including all quantum corrections. We discuss here how it encodes also Noether currents at the ful…
