FWF Projekt ZK 91 "Isolated Strong Optical Magnetic Pulse Spectroscopy"In October 2024, Hongtao Hu was invited to give a talk in the ICAI2024 conference in Xi’an, China.
During the conference, scientific exchange with peers at the conference provided valuable feedback and opened new opportunities for future collaborations.
Xi’an, one of China’s most historic cities, has served as the capital for 13 dynasties throughout history. It is a city that combines ancient history with modernity.
On 29th of September, 2024, some members of iStOMPS went for a hike into the vineyards of Vienna. Although some iStOMPies could not make it, we got reinforcements from the González and Baltuska groups where iStOMPS is located.
From 2nd to 6th of September, Sebastian and several other members of the AG González went to Braunschweig to attend the 60th Symposium on Theoretical Chemistry. The huge conference was very well organized and offered a broad selection of topics from all fields of theoretical chemistry.
From 27th of July to 6th of August, 2024, Sebastian went to the USA. First, at the International Conference on Coordination Chemistry in Fort Collins, Colorado, he was giving an invited lecture on nonadiabatic dynamics simulations of transition metal complexes. He was also presenting many exciting new developments in the SHARC software package, including iStOMPS’ magnetic dipole transitions and works about lanthanide systems.
Subsequently, he flew to Athens, Georgia, to meet a long-term collaborator and to give a seminar presentation in the group of Fritz Schaefer III.
On 24.05.2024, the Lange Nacht der Forschung (Long Night of Research) commenced in Austria. Lorenz, Rahul, and Sebastian from iStOMPS participated in this fantastic event with an exhibit at the main building of the University of Vienna. Together with members of the Backus group (laser spectroscopy), they presented a hand-built, do-it-yourself-style absorption spectrometer for visible light. We (and the visitors) had lots of fun in discovering how colors work. There even was a detective story about the ominous Prof. U. V. Vis for the kids to solve!
The spectrometer consists of easily available parts: an LED torchlight, a reading lens, two playing cards, a simple optical grating, a strip of white paper, and a webcam. The parts are arranged on a plywood frame with some 3D-printed mounts and contained in a black cardboard box that can be closed. When the torchlight is turned on, its light falls on the grating and is split into a rainbow on the paperstrip. The webcam sends pictures of the rainbow to a connected laptop that visualizes the absorption spectrum of colorful foils or table scatter gemstones.
The ACS Photonics article published by Edgar Kaksis and Valentina Shumakova about stimulated Raman scattering for the production of XUV radiation produced quite a lot of Media attention. Have a look for yourself at the News page of the TU Wien Faculty of Electrical Engineering and Information Technology!
More Media echo can be found at Altmetrics.
Some members of iStOMPS published a manuscript on the efficient generation of XUV radiation via high-harmonic generation based on stimulated Raman scattering driven by a Yb-based laser source.

Congratulations to Hongtao for publishing a contribution in the field of time-resolved spectroscopy.

Hello, everyone. My name is Lujia Zhou. I did my Master course in Optical Engineering on Tiangong University and finished in 2021. Now I am a PhD student of the Ultrafast Laser Group in the Institute of Photonics at TU Wien and joining iStOMPS in Subproject B. My task is about the XUV spectroscopy with isolated magnetic fields from laser pulse collision. I hope that I can learn more about optics within the iStOMPS consortium.
On 29.9.2022, Lorenz, Rahul, and Sebastian were joining the European Researchers Night in Vienna and showed young and old guests of the public how to build and use a simple spectrometer to split up visible light and understand the colors of gems and crystals.
