Title: 2D U(1) Chiral Gauge Theory on a Computer

Abstract: This talk will present a method to compute the spectrum of an arbitrary 2D chiral U(1) gauge theory coupled to fermions on a computer using Hamiltonian truncation. The gauge and 't Hooft anomalies are reproduced by the Hamiltonian used in the numerical computation. A validation of the method will be presented for massless 2D QED (the Schwinger model), obtained on a laptop computer running Mathematica. The application of the method to the chiral "543" model is in progress, and is expected to give accurate numerical predictions for the low-lying spectrum of this model using similarly modest computational resources. The generalization to non-Abelian gauge theories and higher dimensions will be discussed.
