The two-flavor Schwinger model at 50: Solving Coleman's puzzles
Gabriel Cuomo, Ross Dempsey, Andrei Katsevich +4
In his 1976 paper "More about the massive Schwinger model", Coleman introduced -dimensional Quantum Electrodynamics coupled to two charged massive fermions. By applying Abelia…
Vacuum structure of gapped QCD theories from the infinite Hamiltonian lattice
Ross Dempsey, Anna-Maria E. Glück, Silviu S. Pufu +1
Gapped two-dimensional gauge theories with massless fermions generically have rich vacuum structures consisting of many degenerate vacua related by the action of topological line o…
Infinite matrix product states for -dimensional gauge theories
Ross Dempsey, Anna-Maria E. Glück, Silviu S. Pufu +1
We present a matrix product operator construction that allows us to represent the lattice Hamiltonians of (abelian or non-abelian) gauge theories in a local and manifestly translat…
Supercurrents and (Partial) Supersymmetry in Adjoint QCD and Its Generalizations
Igor R. Klebanov, Silviu S. Pufu, Benjamin Søgaard +1
-dimensional gauge theory coupled to an adjoint Majorana fermion, also known as adjoint QCD, has the surprising feature that at fermion mass $\sqrt{\frac{g^2 N}{2…
More About the Lattice Hamiltonian for Adjoint QCD
Ross Dempsey, Silviu S. Pufu, Benjamin T. Søgaard +1
In our earlier work arXiv:2311.09334, we introduced a lattice Hamiltonian for Adjoint QCD using staggered Majorana fermions. We found the gauge invariant space of states explic…
Small Circle Expansion for Adjoint QCD with Periodic Boundary Conditions
Ross Dempsey, Igor R. Klebanov, Silviu S. Pufu +1
We study -dimensional gauge theory coupled to one adjoint multiplet of Majorana fermions on a small spatial circle of circumference . Using periodic boundary…
Lattice Hamiltonian for Adjoint QCD
Ross Dempsey, Igor R. Klebanov, Silviu S. Pufu +1
We introduce a Hamiltonian lattice model for the -dimensional gauge theory coupled to one adjoint Majorana fermion of mass . The discretization of the co…
Phase Diagram of the Two-Flavor Schwinger Model at Zero Temperature
Ross Dempsey, Igor R. Klebanov, Silviu S. Pufu +2
We examine the phase structure of the two-flavor Schwinger model as a function of the -angle and the two masses, and . In particular, we find interesting effects at $…
Conformal Carroll Scalars with Boosts
Stefano Baiguera, Gerben Oling, Watse Sybesma +1
We construct two distinct actions for scalar fields that are invariant under local Carroll boosts and Weyl transformations. Conformal Carroll field theories were recently argued to…
Carroll Expansion of General Relativity
Dennis Hansen, Niels A. Obers, Gerben Oling +1
We study the small speed of light expansion of general relativity, utilizing the modern perspective on non-Lorentzian geometry. This is an expansion around the ultra-local Carroll…
