    Here is an interesting paper where they uncover new dualities by studying adjoint QCD in 2 + 1 dimensions.

    Phases Of Adjoint QCD_3 And Dualities

    by Jaume Gomis, Zohar Komargodski, and Nathan Seiberg

    We study 2+1 dimensional gauge theories with a Chern-Simons term and a fermion in the adjoint representation. We apply general considerations of symmetries, anomalies, and renormalization group flows to determine the possible phases of the theory as a function of the gauge group, the Chern-Simons level
    k, and the fermion mass. We propose an inherently quantum mechanical phase of adjoint QCD with small enough k, where the infrared is described by a certain Topological Quantum Field Theory (TQFT). For a special choice of the mass, the theory has N = 1 supersymmetry. There this TQFT is accompanied by a
    massless Majorana fermion – a Goldstino signaling spontaneous supersymmetry breaking. Our analysis leads us to conjecture a number of new infrared fermion-fermion dualities involving SU, SO, and Sp
    gauge theories. It also leads us to suggest a phase diagram of SO/Sp gauge theories with a fermion in the traceless symmetric/antisymmetric tensor representation of the gauge group. As a by-product of our analysis, we conjecture the value of the time-reversal anomaly ν of U (n)_n,2n, SO(n)_n, and Sp(n)_n Chern-Simons theories.

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.
