Bosonization versus the Nielsen-Ninomiya theorem
Saif Ullah Baig, Shi Chen, Aleksey Cherman +1
Thanks to bosonization, bosonic lattice models can offer a lattice regularization of chiral fermions. We construct chiral lattice fermion operators in the 2D modified Villain scala…
Symmetry theta angles and topological Witten effects
Shi Chen, Aleksey Cherman, Maria Neuzil
We introduce a large class of angles in quantum field theory that we call symmetry angles. Unlike conventional angles whose definition depends on a choice of a path int…
Cheshire terms, Aharonov-Bohm effects, and axions
Shi Chen, Aleksey Cherman, Gongjun Choi +1
We discuss unusual terms that can appear in field theories that allow global vortices. These `Cheshire terms' induce Aharonov-Bohm effects for some particles that move arou…
Beta Functions of 2d Adjoint QCD
Aleksey Cherman, Maria Neuzil
We discuss the long-distance physics of 2d adjoint QCD when it is viewed as an effective field theory, and determine the beta functions for its two classically-marginal four-fermi…
1-form symmetry versus large N QCD
Aleksey Cherman, Theodore Jacobson, Maria Neuzil
We show that large N QCD does not have an emergent 1-form symmetry. Our results suggest that a symmetry-based understanding of (approximate) confinement in QCD would…
Universal Deformations
Aleksey Cherman, Theodore Jacobson, Maria Neuzil
QFTs with local topological operators feature unusual sectors called "universes," which are separated by infinite-tension domain walls. We show that such systems have relevant defo…
The Sheet of Giants: Unusual Properties of the Milky Way's Immediate Neighbourhood
Maria K. Neuzil, Philip Mansfield, Andrey V. Kravtsov
We quantify the shape and overdensity of the galaxy distribution in the `Local Sheet' within a sphere of Mpc, and compare these properties with the expectations of the CDM…
