Recent progress in utilizing ultrafast light-matter interaction to control the macroscopic
properties of quantum materials is reviewed. Particular emphasis is placed on photoinduced …

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 …

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 …

We review recent work on low-frequency Floquet engineering and its application to quantum
materials driven by light, focusing on van der Waals systems hosting Moiré superlattices …

Black phosphorus (BP), an elemental semiconductor, has attracted tremendous interest
because it exhibits a wealth of interesting electronic and optoelectronic properties in …

Van der Waals (vdW) materials at their 2D limit are diverse, flexible, and unique laboratories
to study fundamental quantum phenomena and their future applications. Their novel …

The ground states of noninteracting fermions in one-dimension with chiral symmetry form a
class of topological band insulators, described by a topological invariant that can be related …

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

We propose a tunable optical setup to engineer topologically nontrivial flat bands in twisted
bilayer graphene under circularly polarized light. Using both analytical and numerical …

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 …
