“Non-Symmetries, Naturalness, and Two-Dimensional Adjoint QCD”

We will explain the notion of "non-symmetries" or "defect symmetries." We will show that massless two-dimensional QCD admits exponentially many such symmetries. We will use them to prove deconfinement as well as to compute exactly the tension of all k-strings in the small mass limit. Finally, we will discuss quartic fermion deformations and exhibit some unexpected phases which we can determine using the defect symmetries.
