From black holes to badly behaved metals

S. Hartnoll Ripples propagating on the event horizons of black holes precisely mimic the flow of heat and charge through a strongly correlated medium. This remarkable fact builds upon insights from the 70s showing that black holes possess thermodynamics properties. I will describe how this connection, known as holographic duality, has recently lead to new ways of thinking about thermal and electronic transport in unconventional metals. I will argue that, in moving beyond the 100 year old quasiparticle paradigm for transport, these ideas can help to demystify some of the exotic behavior of these materials.
