Mass shift in lattice Hamiltonian approach to Schwinger model
Silviu Pufu,
Princeton University,
The Schwinger model, or quantum electrodynamics in 1+1 dimensions, is one of the simplest gauge theories. In this talk, I will first review a standard lattice discretization of the one-flavor Schwinger model using the Kogut-Susskind Hamiltonian approach with staggered fermions. I will then present a new relation between the lattice and continuum mass parameters, and show how this relation significantly improves the continuum extrapolations of various quantities computed on the lattice. Lastly, I will also discuss aspects of the two-flavor Schwinger model and its phase diagram.
In person attendees (469 Lauritsen) must have a valid Caltech ID.
