The photoexcitation life cycle from incident photon (and creation of photoexcited electron–
hole pair) to ultimate extraction of electrical current is a complex multiphysics process …

Biocatalytic transformations in living organisms, such as multi-enzyme catalytic cascades,
proceed in different cellular membrane-compartmentalized organelles with high efficiency …

The emergence of a topological transition of the polaritonic dispersion in twisted bilayers of
anisotropic van der Waals materials at a given twist angle—the photonic magic angle …

Abstract 2D monolayers supporting a wide variety of highly confined plasmons, phonon
polaritons, and exciton polaritons can be vertically stacked in van der Waals …

Ferroelectricity, a spontaneous and reversible electric polarization, is found in certain
classes of van der Waals (vdW) materials. The discovery of ferroelectricity in twisted vdW …

Photocurrent in quantum materials is often collected at global contacts far away from the
initial photoexcitation. This collection process is highly nonlocal. It involves an intricate …
