We show terahertz nanoscopy of spintronic photocurrents. A key step towards resolving ultrafast spin and charge dynamics on nanoscales. Special thanks to Felix Paries, Reza Rouzegar, Georg von Freymann, Daniel Mittleman and Xiaojun Wu. arxiv.org/abs/2602.20960

AI can improve the design of experiments. “It takes a lot to think this far outside of the accepted solution,” Adhikari said. “We really needed the AI.” www.quantamagazine.org/ai-comes-up-...

Artificial intelligence software is designing novel experimental protocols that improve upon the work of human physicists, although the humans are still “doing a lot of baby-sitting.”

Assume you take a magnet with a complex electronic band structure. Does the photon energy matter when triggering terahertz photocurrents? It is surprisingly insensitive. New preprint: arxiv.org/abs/2507.00977

Femtosecond photocurrents by the Dresselhaus bulk spin-galvanic effect in an inversion-asymmetric ferromagnet
We study ultrafast photocurrents in thin films of a model ferromagnetic metal with broken bulk inversion symmetry, the half-metallic Heusler compound NiMnSb, following excitation with an optical pump ...

Influence of atomic-scale defects on coherent phonon excitations by THz near fields in an STM
Coherent phonons describe the collective, ultrafast motion of atoms and play a central role in light-induced structural dynamics. Here, we employ terahertz scanning tunneling microscopy (THz-STM) to e...

Efficient broadband terahertz generation by above band-gap excitation of the pyroelectric ZnSnN2
Terahertz (THz) radiation is a powerful probe of low-energy excitations in all phases of matter. However, it remains a challenge to find materials that efficiently generate THz radiation in a broad ra...
