Magnetization signatures of light-induced quantum Hall edge states
Jan P. Dahlhaus, Benjamin M. Fregoso, Joel E. Moore
Circularly polarised light opens a gap in the Dirac spectrum of graphene and topological insulator (TI) surfaces, thereby inducing a quantum Hall-like phase. We propose to detect t…
Dynamics of tunneling into nonequilibrium edge states
Benjamin M. Fregoso, Jan P. Dahlhaus, Joel E. Moore
Time-dependent perturbations can drive a trivial two-dimensional band insulator into a quantum Hall-like phase, with protected nonequilibrium states bound to its edges. We propose…
Universal nonequilibrium signatures of Majorana zero modes in quench dynamics
R. Vasseur, J. P. Dahlhaus, J. E. Moore
The quantum evolution after a metallic lead is suddenly connected to an electron system contains information about the excitation spectrum of the combined system. We exploit this t…
Scattering theory of topological phases in discrete-time quantum walks
B. Tarasinski, J. K. Asboth, J. P. Dahlhaus
One-dimensional discrete-time quantum walks show a rich spectrum of topological phases that have so far been exclusively analysed in momentum space. In this work we introduce an al…
