Calendar of Physics Talks Vienna
| Topics on 3d gravity and AdS/CFT |
| Speaker: | Alan Garbarz (Physics Department, University of Buenos Aires) |
| Abstract: | In this talk we will discuss some aspects of three dimensional gravity and the recent attempts to construct its quantum version in a consistent manner via AdS/CFT correspondence. We will start reviewing seminal results in the field, such as Brown-Henneauxs work on asymptotic symmetries, which will play a main role in the discussion. The main idea of Wittens work of 2007 will also be commented due to its
importance in triggering the recent study of others (than GR) gravitational theories in three dimensions. Among these theories, we will discuss the so-called Chiral Gravity, its cousin dubbed Log Gravity, and the more recent New Massive Gravity. These theories are intended to give alternatives for a possible quantum theory of gravity in three dimensions, with notable differences in comparison with GR, such as novel black holes solutions and deformed AdS asymptotics. In addition, possible physically sensible contributions to the partition function will be mentioned, like particle-like singularities and
space-times with torsion.

| Speaker: | Rudolf Grimm (Institut für Experimentalphysik und Institut für Quantenoptik und Quanteninformation, Universität Innsbruck) |
| Abstract: | Atomic ensembles, cooled down to temperatures in the nanokelvin range and trapped in op-tical potentials, represent ideal model systems to study a great variety of quantum phenomena. After a short introduction into the general ideas and methods of the field, I will present a few examples how [..] |
