Higher-Order Floquet Topological Insulators with Anomalous Corner States
@article{Huang2018HigherOrderFT, title={Higher-Order Floquet Topological Insulators with Anomalous Corner States}, author={Biao Huang and W. Vincent Liu}, journal={arXiv: Strongly Correlated Electrons}, year={2018} }
Higher order topological insulators have emerged as a new class of phases, whose robust in-gap "corner" modes arise from the bulk higher-order multipoles beyond the dipoles in conventional topological insulators. Despite rapid theoretical and experimental breakthroughs, all discussions have been constrained to the static scenario due to the lack of specific schemes to compute higher-order dynamical topological invariant. Here we provide a concrete model and explicit constructions of topological…

It is revealed that the contractibility of Fermi surfaces without crossing any time-reversal invariant momentum and the presence of nontrivial Berry phase on Fermani surfaces are two key conditions for the realization of higher-order topological odd-parity superconductors.
