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…

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…
