How well do lattice simulations reproduce the different aspects of the geometric Schwinger model
H. Dilger, H. Joos
TL;DR
This paper evaluates how effectively lattice simulations replicate key features of the geometric Schwinger Model, focusing on topological aspects and anomalies, and compares them with continuum formulations.
Contribution
It demonstrates that lattice formulations successfully reproduce the $U(1)_A$ anomaly and related topological phenomena in the geometric Schwinger Model.
Findings
Lattice simulations reproduce the $U(1)_A$ anomaly.
Lattice captures topological gauge configurations.
Zero modes are accurately represented on the lattice.
Abstract
We compare continuum and lattice formulation of the geometric Schwinger Model on the torus. The lattice reproduces the anomaly, related to non-trivial topological gauge configurations and zero modes.
