The dielectric function of silver is a fundamental quantity related to its electronic structure
and describes its optical properties. However, results published over the past six decades …

Excitons–two-particle correlated electron-hole pairs–are the dominant low-energy optical
excitation in the broad class of semiconductor materials, which range from classical silicon …

The frequency of electric currents associated with charge carriers moving in the electronic
bands of solids determines the speed limit of electronics and thereby that of information and …

Harnessing the carrier wave of light as an alternating-current bias may enable electronics at
optical clock rates. Lightwave-driven currents have been assumed to be essential for high …

Frequency mixing an ultrafast-pulse laser's fundamental and second-harmonic fields in
semiconductors 1, 2, atomic gases 3, 4, and on metal surfaces 5 generates a directional …

The increasingly prominent role of light in information processing makes optoelectronic
devices a technology of fundamental importance. Coherent control of currents in …

Elementary scattering processes in solid matter occur on ultrafast timescales and
photoelectron spectroscopy in the time domain represents an excellent tool for their …

The dynamics of ionized electrons in a plasma can be controlled by synthetic optical fields
composed of the fundamental and the second harmonic of femtosecond optical pulses with …

We investigate the generation of high-order harmonics using laser pulse energies in the few-
μJ range at high repetition rates. We analyse how the conversion efficiency is influenced by …

Using a model methanelike chiral system, we theoretically demonstrate a possibility to
access photoelectron circular dichroism (PECD) by a single experiment with two …
