In quantum materials, emergent functional properties resulting from strong correlations or
electronic topology offer opportunities for new applications. Over the past decade, ultrafast …

Angle-resolved photoemission spectroscopy (ARPES), with its exceptional sensitivity to both
the binding energy and the momentum of valence electrons in solids, provides unparalleled …

Terahertz (THz)-based electron acceleration has potential as a technology for next-
generation cost-efficient compact electron sources. Although proof-of-principle …

Valley degrees of freedom in transition metal dichalcogenides thoroughly influence electron–
phonon coupling and its nonequilibrium dynamics. We conducted a first-principles study of …

Phonon scattering in metals is one of the most fundamental processes in materials science.
However, understanding such processes has remained challenging and requires detailed …

Understanding quantum materials—solids in which interactions among constituent electrons
yield a great variety of novel emergent quantum phenomena—is a forefront challenge in …

The tunability of materials properties by light promises a wealth of future applications in
energy conversion and information technology. Strongly correlated materials such as …

Precisely controlling the microstructure of supported metal catalysts and regulating metal‐

Contrary to continuous phase transitions, where renormalization group theory provides a
general framework, for discontinuous phase transitions such a framework seems to be …

We generate a tabletop pulsed relativistic electron beam at 100 Hz repetition rate from
vacuum laser acceleration by tightly focusing a radially polarized beam into a low-density …
