Lifshitz Space-Times for Schroedinger Holography

Understand

We show that asymptotically locally Lifshitz space-times are holographically dual to field theories that exhibit Schroedinger invariance.

• This involves a complete identification of the sources, which describe torsional Newton-Cartan geometry on the boundary and transform under the Schroedinger algebra.
• We furthermore identify the dual vevs from which we define and construct the boundary energy-momentum tensor and mass current and show that these obey Ward identities that are organized by the Schroedinger algebra.
• We also point out that even though the energy flux has scaling dimension larger than z+2, it can be expressed in terms of computable vev/source pairs.
