Description

Because it offers exactly-integer topological quantities, the modified Villain discretization offers a route to correct anomaly structure at finite lattice spacing. I will present a 4-dimensional purely-bosonic modified Villain model with an ABJ-type vector-vector-axial anomaly.

The model appears to have a direct continuous phase transition from one SSB phase to another, giving hope of discovering a 4D CFT with a VVA anomaly.
