Abstract

Quantum critical strongly correlated systems feature universal collision dominated collective transport Viscous electronics is an emerging field dealing with systems in which strongly interacting electrons flow like a fluid Such flows have some remarkable properties never seen before I shall describe recent theoretical and experimental works devoted in particular to a striking macroscopic DC transport behavior: viscous friction can drive electric current against an applied field resulting in a negative resistance recently measured experimentally in graphene I shall also describe conductance exceeding the fundamental quantum ballistic limit field theoretical anomalies and other wonders of viscous electronics Strongly interacting electron hole plasma in high mobility graphene affords a unique link between quantum critical electron transport and the wealth of fluid mechanics phenomena Refreshments are served at 15:15
