Topological Hydrodynamics in Insulators

Monday, April 29, 2019 - 2:30pm

I will discuss transport phenomena in nonmetallic solid-state systems, which are engendered by the order-parameter topology. Unlike the traditional conservation laws that are rooted in some global symmetry, the hydrodynamics here are governed by the topological structure of the field configurations. I will consider several illustrative examples, including superfluid-like winding dynamics in 1D, vorticity transport in 2D, and skyrmionic flows in 3D, with a discussion of relevant materials and magnetoelectric tools to control and detect the emergent neutral transport.
