Mini-Workshop on Lattice Gauge Theories

2D Lattice Gauge Theory

Lattice Gauge Theories (LGTs) represent an approach to study gauge theories on a discretized spacetime. The picture shows a 2D lattice whose vertices are populated by staggered fermions, while gauge fields live in the links between the vertices. LGTs have a key importance for subatomic and condensed-matter physics as well as topological quantum-information processing.

Two months have passed since the Kick-off of the NeQST project in Innsbruck and the participants working on Lattice Gauge Theories (LGTs) have met a second time. To make the return from the Christmas holidays more exciting, we organized an informal Mini-Workshop at the University of Trento, coordinator of the project. The event took place on January 11 and 12, 2023.

The Mini-Workshop was an opportunity to intensify the connections between the Trento, Trieste, and Barcelona groups working on LGTs and to update on the current fields of interest during the discussion moments. Furthermore, only half of the speakers were from the NeQST project: during the days in Trento, the Mini-Workshop made it possible to establish contacts between participants coming from four different institutions, even external to the project.

There were about 20 participants at the workshop. The topics covered during the talks ranged from Entanglement Witnessing for LGTs, Quantum Simulation of LGTs according to different approaches, Gauge Protection for LGTs, and Quantum Error Correction for LGTs.
