Wonders of viscous electronics
Viscous electronics is an emerging field dealing with high-mobility materials like graphene, where strongly interacting electrons flow like a fluid. Such flows have some remarkable properties never seen before including breakdown of Ohm law. I shall describe recent theoretical and experimental works devoted, in particular, to a striking macroscopic 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 counter-intuitively growing upon heating and exceeding the fundamental quantum-ballistic limit and other wonders of viscous electronics.
