A Vector-Vector-Axial Anomaly in 4D
Evan Berkowitz, Shi Chen, Aleksey Cherman
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…
Generalized BKT Transitions and Persistent Order on the Lattice
Evan Berkowitz, Seth Buesing, Shi Chen +2
The BKT transition in low-dimensional systems with a global symmetry separates a gapless conformal phase from a trivially gapped, disordered phase, and is driven by vortex p…
Exact lattice chiral symmetry in 2d gauge theory
Evan Berkowitz, Aleksey Cherman, Theodore Jacobson
We construct symmetry-preserving lattice regularizations of 2d QED with one and two flavors of Dirac fermions, as well as the `3450' chiral gauge theory, by leveraging bosonization…
