50. Effective actions for fluids from holography

Jan de Boer

4/17/15, 9:00 AM

Effective actions based on scalar fields or Goldstone bosons are frequently used to describe fluids. The precise interpretation of such actions from a gravitational point of view has been somewhat unclear. In this talk I will describe a holographic interpretation of such effective actions and discuss the connection to other approaches to fluid/gravity duality.

38. Torsional Newton-Cartan geometry in Lifshitz holography and non-relativistic field theories

Niels Obers

4/17/15, 10:50 AM

I will discuss recent progress in understanding Lifshitz holography, including the appearance of torsional Newton-Cartan geometry on the boundary. The coupling of non-relativistic field theories to such a geometry will be cosnidered, along with the corresponding symmetry structure for the case of a flat Newton-Cartan background. We will show that, depending on the details of the action, such...

39. How far can we push the AdS/Ricci-flat correspondence?

Marco Caldarelli

4/17/15, 11:20 AM

The AdS/RF correspondence connects classes of Ricci-flat spacetimes to asymptotically anti-de Sitter spacetimes, and thus endows these vacuum gravity solutions with a generalized conformal symmetry and a holographic structure, both inherited from AdS. The precise map requires however the dimensional reduction over a round sphere, and is therefore unsuitable to gain insights into asymptotically...

45. AdS black hole thermodynamics with scalar hair

Ioannis Papadimitriou

4/17/15, 11:50 AM

I will discuss the thermodynamics of asymptotically AdS black holes with scalar hair whose mass lies in the window allowing mixed (multi-trace) boundary conditions. Such boundary conditions on the scalars require a careful definition of the asymptotic charges, but the first law and other thermodynamic properties continue to hold in their usual form.

47. From strange metals to black holes and back: effective theories of thermoelectric transport

Blaise Gouteraux

4/17/15, 12:20 PM

What can Gauge/Gravity duality teach us about Condensed Matter physics? While the search goes on for gravitational duals to strange metals and other strongly-coupled Condensed Matter systems, I'll discuss two specific examples where holographic computations have allowed us to formulate effective theories of thermoelectric transport, the existence of which does not rely on holography or...
