A Non-Relativistic Limit of NS-NS Gravity

In this talk, I describe recent progress in understanding the background field dynamics of the non-relativistic string theory pioneered by Gomis and Ooguri. It is well-known that the underlying string sigma model can be obtained via a limiting procedure — based on a crucial cancellation of infinities — from the relativistic Polyakov model. I show that a similar, subtle limit of the effective supergravity description can be defined — giving rise to a non-relativistic analog of NS-NS gravity. The results are compared with constraints on the background geometry coming from (one-loop) beta function calculations. In the final part of my talk, I will comment on non-relativistic T-duality, p-brane solutions, and potential applications to non-relativistic holography.
