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

Floquet engineering, the control of quantum systems using periodic driving, is an old
concept in condensed matter physics dating back to ideas such as the inverse Faraday …

In Floquet engineering, periodic driving is used to realize novel phases of matter that are
inaccessible in thermal equilibrium. For this purpose, the Floquet theory provides us a recipe …

We overview the concept of dynamical phase transitions (DPTs) in isolated quantum
systems quenched out of equilibrium. We focus on non-equilibrium transitions characterized …

In the last two decades non-equilibrium spectroscopies have evolved from avant-garde
studies to crucial tools for expanding our understanding of the physics of strongly correlated …

Interactions of quantum materials with strong laser fields can induce exotic non-equilibrium
electronic states,,,,–. Monolayer transition metal dichalcogenides, a new class of direct-gap …

The physics of non-equilibrium many-body systems is a rapidly expanding area of
theoretical physics. Traditionally employed in laser physics and superconducting kinetics …

The study of nonequilibrium phenomena in correlated lattice systems has developed into
one of the most active and exciting branches of condensed matter physics. This research …

We construct a systematic high-frequency expansion for periodically driven quantum
systems based on the Brillouin-Wigner (BW) perturbation theory, which generates an …

The bulk photovoltaic effect (BPVE) occurs in solids with broken inversion symmetry and
refers to DC generation due to uniform illumination, without the need of heterostructures or …
