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…
Stable vortex loops in two-species BECs
Paulo F. Bedaque, Evan Berkowitz, Srimoyee Sen
We consider the creation of stable, stationary closed vortex loops, analogue to the vortons and superconducting cosmic strings, in cold atom BEC's. We explore the parameter region…
