Holography and Gravity between Newton and Einstein


Abstract: Newton-Cartan geometry was introduced more than 90 years ago in order to find a geometric formulation of Newtonian gravity. This geometry (including a novel generalisation that includes torsion) has in recent years gained renewed interest as it appears in a variety of settings in modern theory involving gravity, string theory and holography.  In particular, torsional Newton-Cartan geometry has been shown to appear as the boundary geometry for Lifshitz spacetimes. which is a holographic setup for systems with non-relativistic symmetry. The reason is that non-relativistic field theories naturally couple to such geometries, in the same way that relativistic field theories couple to Riemannian geometry. Furthermore, non-relativistic geometry and gravity appears in limits of string theory and the AdS/CFT correspondence. This includes novel Chern-Simons theories of gravity in three dimensions which follow from a well-defined limit of the AdS3/CFT2 correspondence, which I will discuss. I will also comment on how non-relativistic strings move in a Newton-Cartan target space, and a further worldsheet limit which is related to limits of AdS5/CFT4. Finally, I will talk about recent work on understanding non-relativistic gravity (including its Newtonian limit) from a new perspective.

About

This event is part of a regular series of meetings sponsored by Delta ITP with the objective of bringing together the theoretical physics communities in Amsterdam, Leiden, Utrecht and our sister nodes Groningen, Brussels (ULB and VUB) and Leuven. The topic of this meeting is holography and its applications to different physical systems. We encourage researchers from different areas in theoretical physics to participate!
