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

When the continuous symmetry of a physical system is spontaneously broken, two types of
collective modes typically emerge: the amplitude and the phase modes of the order …

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

Advances in light sources and time-resolved spectroscopy have made it possible to excite
specific atomic vibrations in solids and to observe the resulting changes in electronic …

Light-induced supercurrents chart a path forward for the electromagnetic design of emergent
materials phases and collective modes for quantum engineering applications. However …

The Higgs mechanism, ie, spontaneous symmetry breaking of the quantum vacuum, is a
cross-disciplinary principle, universal for understanding dark energy, antimatter and …

Abstract 'Sudden'quantum quench and prethermalization have become a cross-cutting
theme for discovering emergent states of matter,,–. Yet this remains challenging in electron …

Recent findings of new Higgs modes in unconventional superconductors require a
classification and characterization of the modes allowed by nontrivial gap symmetry. Here …

Characterizing and controlling high-order correlation of quantum systems is key for
develo** quantum devices and switching technologies. Although conventional static and …

We study thermalization dynamics in a fermion-phonon variant of the Sachdev-Ye-Kitaev
model coupled to an external cold thermal bath of harmonic oscillators. We find that …
