Key properties of quantum materials stem from dynamic interaction chains that connect
stable electronic quasiparticles through short-lived coherences, which are difficult to control …

In the past 20 years, we have reached a broad understanding of many light-driven
phenomena in nanoscale systems. The temporal dynamics of the excited states are instead …

The primary step of almost any interaction between light and materials is the electrodynamic
response of the electrons to the optical cycles of the im**ing light wave on sub …

The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

Tailoring the electric-field waveform of ultrashort light pulses forms the basis for controlling
nonlinear optical phenomena on their genuine, attosecond timescale. Here we extend …

The current revolution in information technology is built on the development of
semiconductor transistors and electronics over several decades. However, these electronics …

Free electrons are essential in such diverse applications as electron microscopes,
accelerators and photoemission spectroscopy. However, the space charge effects of many …

We demonstrate an on-chip, optoelectronic device capable of sampling arbitrary, low-
energy, near-infrared waveforms under ambient conditions with sub-optical-cycle resolution …

High-order harmonic generation (HHG) in gases is frequently used nowadays to produce
attosecond pulses and coherent radiation in the visible-to-soft X-ray spectral range. HHG in …
