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

The advent of pump-probe spectroscopy techniques paved the way to the exploration of
ultrafast dynamics of electrons and phonons in crystalline solids. Following photo-absorption …

Direct optical probing of the antiferromagnetic order parameter in atomically thin samples is
challenging, for example, via magneto-optical spectroscopy, due to the lack of net …

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

A grand challenge underlies the entire field of topology-enabled quantum logic and
information science: how to establish topological control principles driven by quantum …

We report terahertz (THz) light-induced second harmonic generation, in superconductors
with inversion symmetry that forbid even-order nonlinearities. The THz second harmonic …

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 …

Topology-protected surface transport of ultimate thinness in three-dimensional topological
insulators (TIs) is breaking new ground in quantum science and technology. Yet a challenge …

We review our recent experimental results on the electronic nematic phase in electron-and
hole-doped BaFe 2 As 2 and FeSe. The nematic susceptibility is extracted from shear …
