Graphene irradiated by a circularly polarized laser has been predicted to be a Floquet
topological insulator showing a laser-induced quantum Hall effect. A circularly polarized …

Results are presented for the optical Hall conductivity of a Floquet topological insulator (FTI)
for an ideal closed quantum system, as well as an open system in a nonequilibrium steady …

We report on simulations of the dc conductance and quantum Hall response of a Floquet
topological insulator using Floquet scattering theory. Our results reveal that laser-induced …

We show that an energy gap is induced in graphene by light-matter coupling to a circularly
polarized photon mode in a cavity. Using many-body perturbation theory, we compute the …

Non-equilibrium topological phenomena can be induced in quantum many-body systems
using time-periodic fields (for example, by laser or microwave illumination). This Review …

We develop a theory of topological transitions in a Floquet topological insulator, using
graphene irradiated by circularly polarized light as a concrete realization. We demonstrate …

Floquet topological insulators are systems in which the topology emerges only when a time-
periodic perturbation is applied. In these systems one can define quasienergy states which …

In the presence of a circularly polarized mid-infrared radiation graphene develops
dynamical band gaps in its quasienergy band structure and becomes a Floquet insulator …

Motivated by the quest for experimentally accessible dynamical probes of Floquet
topological insulators, we formulate the linear response theory of a periodically driven …

Floquet topological insulators are noninteracting quantum systems that, when driven by a
time-periodic field, are described by effective Hamiltonians whose bands carry nontrivial …
