Non-relativistic limits of supersymmetric Yang-Mills theory and S-duality
Hyungrok Kim, Joseph Smith
We investigate non-relativistic limits of four-dimensional maximally supersymmetric Yang-Mills theory (4d MSYM) and their relation to the nonperturbative $\operatorname{SL}(2;\math…

A Note on the Perturbative Expansion of the Schwinger Model on
Joseph Smith
The Schwinger model is perhaps the simplest non-trivial exactly-solvable QFT. In this note we examine the perturbative structure of the theory on the sphere and show that its quant…

The M5-Brane Limit of Eleven-Dimensional Supergravity
Eric Bergshoeff, Neil Lambert, Joseph Smith
We construct the M5-brane limit of eleven-dimensional supergravity. The resulting action is invariant under Galilean boosts and has a local scale symmetry. We also consider the lim…
