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 …

Electronic states in quantum materials can be engineered by light irradiation, which is
greatly advanced by ab-initio computational predictions in realistic light-matter coupled …

We report on the emergence of laser-induced chiral edge states in graphene ribbons.
Insights on the nature of these Floquet states is provided by an analytical solution which is …

Periodically driven (Floquet) systems have been under active theoretical and experimental
investigations. This paper aims at a systematic study in the following aspects of Floquet …

The Su–Schrieffer–Heeger model of polyacetylene is a paradigmatic Hamiltonian exhibiting
nontrivial edge states. By using Floquet theory we study how the spectrum of this one …

Second-order topological insulators (SOTI) exhibit protected gapless boundary states at
their hinges or corners. In this paper, we propose a generic means to construct SOTIs in …

Artificial gauge fields enable uncharged particles to behave as if affected by external fields.
Generated by geometry or modulation, artificial gauge fields are instrumental in realizing …

Electromagnetic driving in a honeycomb lattice can induce gaps and topological edge states
with a structure of increasing complexity as the frequency of the driving lowers. While the …

Recent experiments showed that the surface of a three-dimensional topological insulator
develops gaps in the Floquet-Bloch band spectrum when illuminated with a circularly …

We describe an experimental setup for imaging topologically protected Floquet edge states
using ultracold bosons in an optical lattice. Our setup involves a deep two-dimensional …
