Query: Magnetization signatures of light-induced quantum Hall edge states   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 the accompanying edge states and their current by
the magnetic field they produce. The topological nature of the edge states is
reflected in the mean orbital magnetization of the sample, which shows a
universal linear dependence as a function of a generalized chemical potential -
independent of the driving details and the properties of the material. The
proposed protocol overcomes several typically encountered problems in the
realization and measurement of Floquet phases, including the destructive
effects of phonons and coupled electron baths and provides a way to occupy the
induced edge states selectively. We estimate practical experimental parameters
and conclude that the magnetization signature of the Floquet topological phase
may be detectable with current techniques.
