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…
