# Theta dependence in lattice gauge theories: physics and algorithms

#### Theta dependence in lattice gauge theories: physics and algorithms

- Event time: 2:00pm
- Event date: 21st March 2018
- Speaker: Dr Claudio Bonati (Pisa)
- Location: Higgs Centre Seminar Room, 4305 James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

The aim of this talk is to give a broad overview of the physics related to theta dependence in gauge theories and to the problems encountered in studying such topics by using lattice simulations. While these problems are generically classified as algorithmic problems, their origin can in fact be understood using simple physical arguments. These arguments also make it clear that this class of problems is typical not only of 4d gauge theories, but also of much simpler low dimensional theories, that can be conveniently used as test beds for algorithm development.
