ICMT Seminar: "Topological quantum dynamics in periodically driven systems"
(sign-up)Andrew Potter, University of Texas at Austin
Institute for Condensed Matter Physics
Time-periodic driving enables non-equilibrium topological phases with dynamical properties that are not possible in thermal equilibrium. Striking examples include i) Floquet symmetry-protected topological phases (FSPT) of chains of spins or qubits, and ii) 2d chiral-Floquet phases whose edges act as unidirectional quantum channels that transfer a quantized amount of information per driving period. I will review recent progress in classifying these phases, and propose experimental realizations and schemes to measure their dynamical topological invariants.
