Julian Sonner will give a talk, September 8, 2011, titled “Holographic Fermi Surfaces: The view from the Top Down”, in SCGP Room 102 at 11:15am
Abstract: Strongly interacting fermions at finite density are infamously hard to treat. Gauge/gravity duality gives a way of studying them in a controlled environment. For such studies to be reliable it is important that the models are eventually embedded in M-theory (or string theory). In this talk I will describe how to look for some of the most basic features of fermionic finite-density states in M-theory, such as the occurrence of Fermi surfaces, and describe the wider implications of our recent intriguing results on these objects.
