Description
I will discuss quantum properties of galilean N=2 supersymmetric theories in d =2+1, primarily focusing on the non-relativistic version of the Wess-Zumino model and SuperQED. Compared with their relativistic cousins, these models exhibit very different behavior. The non-relativistic Wess-Zumino model is one-loop exact, as a consequence of robust non-renormalisation theorems. The non-relativistic electrodynamics is featured by an infinite number of marginal couplings that turn on along the RG flows. Superconformal invariance is preserved in correspondence of a non-trivial conformal manifold of fixed points where the theory is gauge-invariant and interacting.
