Localized Photon Absorption in a Single-Crystalline Material
Daniel Kazenwadel, Jacob Holder, Livio Ciorciaro +6
The absorption of light is one of the most fundamental processes in condensed-matter physics and optics. Here we investigate under which conditions laser light is absorbed by a cry…

Electron modulation and ultrafast near-field imaging with vectorial laser fields
J. Kuttruff, L. Möhrle, L. Ciorciaro +2
Controlled interaction of laser light with electron beams is fundamental for ultrafast electron microscopy and electron-based quantum optics, yet their direct coupling is forbidden…

AC-Stark Spectroscopy of Interactions between Moiré Excitons and Polarons
B. Evrard, H. S. Adlong, A. A. Ghita +6
We use nonlinear pump-probe spectroscopy to study optical excitations in a charge-tunable MoSe\WS moiré heterostructure. An intense red-detuned laser pulse creates a photo…
