FWF Projekt ZK 91 "Isolated Strong Optical Magnetic Pulse Spectroscopy"

From the 12th to 14th of March, Optica High-Brightness Sources and Light-Driven Interactions Congress took place in Vienna, Austria. The Congress was comprised of three topical meetings: High-Intensity Lasers and High-Field Phenomena (HILAS), Compact EUV & X-Ray Light Sources (EUVXRAY), and Mid-Infrared Coherent Sources (MICS). The event covered many topics on laser technologies, high-brightness sources, attosecond science, and light-driven interactions.

Liza attended the Congress and presented the poster titled “Spectrally Selective Excitation of Electric Dipole and Magnetic Dipole Transitions in Eu³⁺Y₂O₃ Nanostructures” on the HILAS topical meeting. In addition to the useful insights on the various aspects of the laser physics, it was interesting to learn about the promising role of Eu³⁺ ions in the development of solid-state red lasers.

From 4 to 15 September 2023, I participated in the 2023 European School on Magnetism (ESM 2023). The topic was “Nanomagnetism for emerging technologies”, and the school was held in a mixed format: both onsite in Madrid, Spain, and online. The online lectures and tutorials covered a wide range of topics from fundamentals of magnetism to advanced detection and fabrication techniques, as well as modern applications. I also used the chance to present our work online and was awarded a poster prize, which included a voucher for free attendance to the International Conference on Magnetism conference ICM2024 to be held in Bologna. I am looking forward to attending this conference, which would provide a great opportunity for further networking and sharing iStOMPS ideas among the magnetic community.

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.

On June 26-30, 2023, Lorenz and Elizaveta attended the Conference on Lasers and Electro-Optics/Europe – European Quantum Electronics Virtual Conferences (CLEO®/Europe-EQEC 2023), which took place in Munich, Germany. CLEO®/Europe-EQEC 2023 are Europe’s largest conferences on photonics, laser technology, and related research fields. The conference program featured plenary and keynote lectures, tutorials, talks, and poster sessions. We also visited the huge exhibition LASER World of PHOTONICS to see the latest trends and innovations in photonics industry.

Elizaveta delivered a talk titled “Generation of Tunable Narrowband Azimuthally Polarized Pulses for Magnetic Excitation of Eu³⁺ Ions” in the session “Ultrafast Spectroscopy”. She described a developed experimental setup for generation of narrowband spectrally tunable ultrafast pulses with azimuthal polarization.

Lorenz presented a poster “Particle-in-Cell simulations of ultrashort optical laser pulses for magnetic field enhancement and electric field suppression” with his investigations of metallic apertures of various shapes and their role in the magnetic field enhancement.

We enjoyed the diverse scientific program, social dinner, networking, meeting our collaborators, as well as Munich sightseeing and cultural events.
