Emergent 1-form symmetries
Aleksey Cherman, Theodore Jacobson
We explore the necessary conditions for 1-form symmetries to emerge in the long-distance limit when they are explicitly broken at short distances. A minimal requirement is that the…
Modified Villain formulation of abelian Chern-Simons theory
Theodore Jacobson, Tin Sulejmanpasic
We formulate Chern-Simons theory on a Euclidean spacetime lattice using the modified Villain approach. Various familiar aspects of continuum Chern-Simons theory such as le…
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…
Four-fermion deformations of the massless Schwinger model and confinement
Aleksey Cherman, Theodore Jacobson, Mikhail Shifman +2
We consider the massless charge- Schwinger model and its deformation with two four-fermion operators. Without the deformations, this model exhibits chiral symmetry breaking with…
Vortices in spin-0 superfluids carry magnetic flux
Aleksey Cherman, Theodore Jacobson, Srimoyee Sen +1
Vortices in spin- superfluids generically carry magnetic fields inside their cores, so that even neutral superfluid vortices may be thought of as magnetic flux tubes. We give a…
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…
Lifetimes of (near) eternal false vacua
Aleksey Cherman, Theodore Jacobson
We consider examples of long-lived false vacua in quantum field theory that arise from so-called `universes'. These false vacua are protected by a -form global symmetry, whe…
Higgs-confinement phase transitions with fundamental representation matter
Aleksey Cherman, Theodore Jacobson, Srimoyee Sen +1
We discuss the conditions under which Higgs and confining regimes in gauge theories with fundamental representation matter fields can be sharply distinguished. It is widely believe…
Anomalies, a mod 2 index, and dynamics of 2d adjoint QCD
Aleksey Cherman, Theodore Jacobson, Yuya Tanizaki +1
We show that d adjoint QCD, an gauge theory with one massless adjoint Majorana fermion, has a variety of mixed 't Hooft anomalies. The anomalies are derived using a rece…
Electromagnetic analogue space-times, analytically and algebraically
Sebastian Schuster, Matt Visser
While quantum field theory could more aptly be called the "quantum field framework" as it encompasses a vast variety of varying concepts and theories in comparison, relativ…
Non-Perturbative One-Loop Effective Action for QED with Yukawa Couplings
Theodore N. Jacobson, Tonnis ter Veldhuis
We derive the one-loop effective action for scalar, pseudoscalar, and electromagnetic fields coupled to a Dirac fermion in an extension of QED with Yukawa couplings. Using the Schw…
