Journal ArticleDOI
Topological characterization of periodically driven quantum systems
TL;DR: In this paper, the authors show that the Floquet operators of periodically driven systems can be divided into topologically distinct (homotopy) classes and give a simple physical interpretation of this classification in terms of the spectra ofFloquet operators.
Journal ArticleDOI
Entanglement spectrum of a topological phase in one dimension
TL;DR: In this paper, it was shown that the Haldane phase is characterized by a double degeneracy of the entanglement spectrum, which cannot be lifted unless either a phase boundary to another, topologically trivial, phase is crossed, or the symmetry is broken.
Journal ArticleDOI
Anomalous Edge States and the Bulk-Edge Correspondence for Periodically Driven Two-Dimensional Systems
Mark S. Rudner,Mark S. Rudner,Mark S. Rudner,Netanel H. Lindner,Erez Berg,Erez Berg,Michael Levin +6 more
TL;DR: In this paper, a topological invariant for periodically driven systems of noninteracting particles is proposed, based on the analysis of the Floquet spectra of driven systems and the band structures of static Hamiltonians.
Journal ArticleDOI
Odd-Parity Topological Superconductors: Theory and Application to CuxBi2Se3
TL;DR: This Letter provides a sufficient criterion for realizing time-reversal-invariant topological superconductor in centrosymmetric superconductors with odd-parity pairing, and proposes that CuxBi2Se3 is a good candidate for a topologicalsuperconductor.
Journal ArticleDOI
Symmetry protection of topological phases in one-dimensional quantum spin systems
TL;DR: In this paper, the Haldane phase in integer spin chains is shown to be a topologically nontrivial phase which is protected by any one of the following three global symmetries: (i) the dihedral group of rotation about the $x, $y, and $z$ axes, (ii) time-reversal symmetry, and (iii) link inversion symmetry.
