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…
