Maths HEP Lunchtime Seminars: Umklapp and AdS/CFT
11 May 2012 13:00 in CM101
I'll discuss different models of quantum criticality at finite density that arise naturally from AdS/CFT. I'll review their properties and focus, in particular, in the conductivity. I'll explain why, if we are interested in dc conductivities, it is crucial to include the effects of leading irrelevant contributions. Finally, I will discuss how we can apply this insight to calculate conductivities in holographic locally critical theories.
