Journal ArticleDOI
Floquet topological insulators
TL;DR: In this article, the authors outline the recent research on topological insulators in non-equilibrium situations and introduce the Floquet formalism that allows to describe steady states of the electronic system with an effective time-independent Hamiltonian.
Journal ArticleDOI
Tunable Band Gap in Hydrogenated Quasi-Free-Standing Graphene
Danny Haberer,Denis V. Vyalikh,Simone Taioli,Balázs Dóra,Mani Farjam,Jörg Fink,Dmitry Marchenko,Thomas Pichler,Klaus Ziegler,Stefano Simonucci,M. S. Dresselhaus,Martin Knupfer,Bernd Büchner,Alexander Grüneis +13 more
TL;DR: It is shown by angle-resolved photoemission spectroscopy that a tunable gap in quasi-free-standing monolayer graphene on Au can be induced by hydrogenation, and thereby provides a model system to study hydrogen storage in carbon materials.
Journal ArticleDOI
Optically Engineering the Topological Properties of a Spin Hall Insulator
TL;DR: Time-periodic perturbations can be used to engineer topological properties of matter by altering the Floquet band structure and the connection with Thouless' charge pumping and nonequilibrium zitterbewegung is discussed, together with possible experiments.
Journal ArticleDOI
Topological classification of dynamical phase transitions
Szabolcs Vajna,Balázs Dóra +1 more
TL;DR: In this paper, it was shown that topology-changing quenches are always followed by nonanalytical temporal behavior of return rates (logarithm of the Loschmidt echo), referred to as dynamical phase transitions (DPTs) in the literature.
Journal ArticleDOI
Disentangling dynamical phase transitions from equilibrium phase transitions
Szabolcs Vajna,Balázs Dóra +1 more
TL;DR: In this paper, Heyl et al. showed that the dynamical free energy on the real time axis does not indicate the presence or absence of an EPT in the transverse field Ising model.
