On 8th of October, Lorenz started his conference travel to China. As the first stop of his itinerary, he visited Prof. Jin Wen and her research group at Donghua University, Shanghai.

In his presentation, Lorenz talked about his research in performing optical absorption spectroscopy with isolated magnetic fields. After a nice discussion, Lorenz was invited to lunch, where he enjoyed authentic Chinese cuisine 🙂 During his stay in Shanghai, Lorenz got some insight in the local research infrastructure of Donghua University and to the work of the students in the research group of Prof. Jin Wen.

After the stay in Shanghai, Lorenz continued his trip to Qingdao, where the 11th Triennial Congress of the International Society for Theoretical Chemical Physics (ISTCP 2024) took place. Lorenz enjoyed the widespread scientific program, networking, and the vivid exchange with colleagues in the same research direction.

In his poster session, Lorenz had the chance to present his research about “Coupling simulations of spatiotemporal electromagnetic fields with simulations of ultrafast photoinduced dynamics” to many conference participants and could talk to other poster presenters in the two other poster sessions.
At the final day of the conference, Lorenz was awarded the best poster prize, which included a lifetime license for the quantum chemistry program Q-Chem and a money prize. Congratulations!

From 12.09.2024 to 13.09.2024, Lorenz and Rahul joined the annual DoSChem Student Symposium, which was held the 4th time since the Doctoral School in Chemistry (DoSChem) was established. Next to interesting contributed talks by fellow PhD students from different fields in Chemistry, Lorenz and Rahul had the chance to listen to the inspiring keynote talks of Prof. Dr. Shana Sturla (ETH Zürich), Prof. Dr. Johannes Messinger (Uppsala University).

Certainly, a highlight of the symposium was the talk given by the pioneer of “supramolecular chemistry” and nobel laureate Prof. Dr. Jean-Marie Lehn about chemical steps towards complex matter.

During the symposium, Lorenz and Rahul both presented their posters about “Simulations of Ultrafast Photoinduced Dynamics with Tailored Electromagnetic Fields” and “Accurate and Efficient Multi-Reference Electronic Structure Calculations for Lanthanide Ions using Selected Spin-Orbit Couplings Interaction” to their interested colleagues.

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.
