Welcome to the webpage of the GRK 2905 (english: Research Training Group RTG 2905). Here you will find all information about upcoming events and latest news. It will be located in the globally unique interdisciplinary environment of the newly emerging research center RUN (Regensburg Center for Ultrafast Nanoscopy).
The RTG 2905 offers a variety of events during the semester, including colloquia, special lecture series, seminars, and workshops. Our mission is to connect students and researchers with the latest scientific developments in ultrafast nanoscopy. All colloquia and special lecture series take place during the semester on Fridays at 2:00 pm in the RUN Auditorium. Seminars also take place regularly. Rooms and times may vary, so please check the announcements for details.

A quantum leap in optical microscopy

2. March 2026

Using a conventional tabletop mid-infrared laser, we observed optical signals modulated on Ångström length scales. These signatures stem from light emission from tunneling currents flowing between the most frontier atom of a metallic tip and a sample surface and are driven by the oscillating electric field of the laser light.This tunneling-mediated contrast emerges under relatively…
