Reading quantum gravity off its boundary
What we work on
Quantum gravity & string theory
Quantum gravity explores gravitational physics at length scales where quantum effects become significant — a regime that neither general relativity nor quantum field theory describes on its own. String theory is currently the most promising candidate for such a theory, so understanding its physical implications is the starting point of our work.
Holographic duality
Holography states that a string theory on a (d+1)-dimensional anti-de Sitter space, together with a (9−d)-dimensional internal manifold, is equivalent to a d-dimensional conformal field theory living on the conformal boundary — the AdS/CFT correspondence. It gives one of the most concrete routes to string theory as a theory of quantum gravity: the physics of strings in AdS can be read off from the dual CFT.
