From 13.09.2023 to 15.09.2023, Liza and Lorenz attended the AttoChem Young Scientist Symposium 2023, which was held in Vienna. The Symposium was organized by a team of scientists at TU Wien, including part of the iStOMPS team – Alessandra, Hongtao, and Liza. The very open and interactive format, including a panel discussion at the last day of the symposium, allowed us to catch a peek into the “Atto Universe”. Liza and Lorenz had the opportunity to show their work within iStOMPS in both flash presentations as well as individual posters:

Lorenz showed his most recent results from Finite-Differences Time-Domain (FDTD) simulations on his poster “Magnetic-only Optical Spectroscopy with Ultrafast Laser Pulses”.

Liza presented the experimental setups (for details see Subproject A, Subproject B) for magnetic-only optical spectroscopy on her poster “Generation of Isolated Strong Transient Magnetic Fields for Magneto-Optical Spectroscopy”.

In July, Lorenz and Rahul represented iStOMPS on the 3^rd International Student Symposium of the Doctoral School in Chemistry, that took place in Vienna.
As a major event of the year the DoSChem symposium gathers students and faculty from different fields in Chemistry, allowing the students to present their research and to interact and exchange on all levels.

On this event, Lorenz gave a talk about “Particle-In-Cell Simulations for Magneto-Only Optical Spectroscopy”, in which he explained the numerical simulations within the iStOMPS project and its implications from a chemical perspective. Moreover, he outlined the possible applications and the impact for spectroscopy.
Rahul on the other hand, presented a poster “Computing Energies with Minimal Effort (for the computer)“, in which he presented a scheme for computing accurate energies for Eu³⁺ ion efficiently. The new method is based on selecting only the states that couple with each other for a perturbation theory treatment.

From 5.3. to 10.3.2023, Lorenz attended the DPG Spring Meeting of the Atomic, Molecular, Quantum Optics and Photonics Section (SAMOP) which took place in Hannover in Germany. He presented a poster about simulations of magnetic field amplification and electric field suppression in ultrashort optical laser pulses.

In his poster, he explained the potential of differently shaped metal apertures to locally enhance the magnetic field while surpresssing the electric field. These findings deliver valuable information for the experimental realization of Sub-Project A. Next to the inspiring talks and poster presentations of an overall quite young scientific community he enjoyed the trip to the PTB Braunschweig very much.
