I will summarize recent work on gauge theories in supergravity, specifically concerning the `Fayet-Iliopoulos' parameter. In rigidly supersymmetric gauge theories, this parameter also appears and can vary continuously. In supergravity old lore held that it should always vanish. I will discuss recent developments showing that in fact it can be nonzero, but is quantized, and will explore...

This presentation reports on the effort to create a mathematical theory for off-shell supersymmetry that is analogous to the construction or roots and weights for Lie groups. The construction begins with the introduction of Adinkras, diagram analogous to weight space representation for quarks. Recent surprising results are discussed.

I will introduce a simple prescription for computing real-time finite temperature n-point functions in AdS/CFT. When used to compute the stopping distance of a highly energetic jet moving through strongly coupled N=4 superYang-Mills plasma, the typical jet stopping distance scales with energy as (EL)^{1/4}, where L is the size of the region where the jet was created.

Holographic models of superconductivity offer a promising approach to the understanding of strongly coupled superconductors. Their properties are derived from non-linear field equations which are hard to solve, especially at low temperatures. I will discuss analytic tools that generate solutions down to zero temperature. This exploration is important for the understanding of the ground state...
