Topological phases of matter in nonequilibrium: Topology of the Wannier-Stark ladder


Dr. Kwon Park

Mar. 11 (Fri.), 1:30 PM, E6-2. 1st fl. #1501


Topological phases of matter are novel phases of matter characterized by the topological invariants describing the topological order. Conventionally, the topological invariants are not directly measured, but instead inferred from the properties of the edge/surface states. In this talk, it is shown that the topological order can be directly manifested in the bulk under a nonequilibrium situation. Specifically, the topological invariants can be directly manifested in the topology of the Wannier-Stark ladder emerging under an electric field.
