High-harmonic spectroscopy, an ultrafast all-optical technique initially conceptualized in
atomic and molecular systems, has now emerged as a powerful platform for studying the …

Arginine methylation of histones plays a critical role in regulating gene expression. The
writers (methyltransferases) and readers of methylarginine marks are well-known, but the …

Time-periodic light field can dress the electronic states and lead to light-induced emergent
properties in quantum materials. While below-gap pum** is regarded favorable for …

Abstract Two-dimensional (2D) Dirac materials, eg, graphene and transition metal
dichalcogenides (TMDs), are one-atom-thick monolayers whose electronic behaviors are …

Excitons are neutral excitations that are composed of electrons and holes bound together by
their attractive Coulomb interaction. The electron and the hole forming the exciton also …

Coherent interaction between light and matter generates photon-dressed replicas of the
original electronic levels (that is, Floquet states). This opens up a so-called field of Floquet …

Excitons play a key role in the linear optical response of two-dimensional (2D) materials.
However, their role in the nonlinear response to intense, nonresonant, low-frequency light is …

Strong light-matter interaction provides opportunities for tailoring the physical properties of
quantum materials on the ultrafast timescale by forming photon-dressed electronic states, ie …

In recent years, the stacking and twisting of atom-thin structures with matching crystal
symmetry has provided a unique way to create new superlattice structures in which new …

The Hall response can be dramatically different from its quantized value in materials with
broken inversion symmetry. This stems from the leading Hall contribution beyond the linear …
