Chiral high-harmonic generation and spectroscopy on solid surfaces using polarization-tailored strong fields
Tobias Heinrich, Marco Taucer, Ofer Kfir +4
Strong-field methods in solids enable new strategies for ultrafast nonlinear spectroscopy and provide all-optical insights into the electronic properties of condensed matter in rec…
Clocking plasmon nanofocusing by THz near-field streaking
Lara Wimmer, Benjamin Schröder, Murat Sivis +2
We apply terahertz (THz) near-field streaking in a nanofocusing geometry to investigate plasmon polariton propagation on the shaft of a conical nanotip. By evaluating the delay bet…
Controlling free electrons with optical whispering-gallery modes
Ofer Kfir, Hugo Lourenço-Martins, Gero Storeck +5
Free-electron beams serve as uniquely versatile probes of microscopic structure and composition, and have repeatedly revolutionized atomic-scale imaging, from solid-state physics t…
Nanoscale Magnetic Imaging using Circularly Polarized High-Harmonic Radiation
Ofer Kfir, Sergey Zayko, Christina Nolte +10
This work demonstrates nanoscale magnetic imaging using bright circularly polarized high-harmonic radiation. We utilize the magneto-optical contrast of worm-like magnetic domains i…
