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

In the last two decades non-equilibrium spectroscopies have evolved from avant-garde
studies to crucial tools for expanding our understanding of the physics of strongly correlated …

Nonlinear optical phenomena are crucial for a broad range of applications, such as
microscopy, all-optical data processing, and quantum information. However, materials …

The size and operating energy of a nonlinear optical device are fundamentally constrained
by the weakness of the nonlinear optical response of common materials. Here, we report …

Recent reports have shown that plasmonic nanostructures can be used to drive direct
photocatalysis with visible photons, where nanostructures act as the light absorber and the …

All-optical control of plasmons can enable optical switches with high speeds, small footprints
and high on/off ratios. Here we demonstrate ultrafast plasmon modulation in the near …

Surface plasmons provide a pathway to efficiently absorb and confine light in metallic
nanostructures, thereby bridging photonics to the nano scale. The decay of surface …

The dependence of the strength of the electron-phonon coupling and the electron heat
capacity on the electron temperature is investigated for eight representative metals, Al, Cu …

Surface plasmons have recently been harnessed to carry out processes such as
photovoltaic current generation, redox photochemistry, photocatalysis, and photodetection …

This review focuses on the generation of energetic (hot) electrons in plasmonic
metastructures and nanomaterials, and their characterization through time-resolved …
