Abstract: The 1+1-dimensional adjoint QCD theory (namely SU(N) gauge theory coupled to a Majorana fermion in the adjoint representation of the gauge group) has two curious properties.  When the fermion is massless, the theory exhibits screening of probe external quarks;  and at a certain non-zero ratio of the fermion mass to the gauge coupling, the theory exhibits (1, 1) supersymmetry.  I will shed some new light onto these properties by placing this theory on a small spatial circle, and through other methods.
