Title: 
Lower Spin Gravity for Warped Holography
Abstract: 

Two dimensional Warped Conformal Field Theories (WCFTs) may represent the simplest examples of field theories without Lorentz invariance that can be described holographically. As such they constitute a natural window into holography in non AdS space-times, including the near horizon geometry of generic extremal black holes. In this talk we explore how WCFTs couple to a background geometry and we find that this geometry is not Riemannian. It turns out to be a variant of a Newton-Cartan structure with additional scaling symmetries. We then construct bulk holographic duals of WCFTs and argue that the minimal setup is not Einstein gravity but an SL(2,R) x U(1) Chern-Simons Theory, which we call Lower Spin Gravity.
