Speaker: Matteo Baggioli

Abstract：

I will discuss why and how to introduce momentum dissipation into the framework of the gauge-gravity duality with particular emphasis on the condensed matter applications. I will review the most relevant models  and how to extract the thermoelectric conductivities within them. As a physical and interesting utilization I will present the recent developments about the possible existence of universal bounds on  conductivities and diffusivities linked with quantum chaos.
