Radostina_Zidarova_Physikerin.jpg

Radostina is a Ph.D. student conducting fundamental research in nuclear physics at TU Darmstadt. She aims to explore the properties of exotic radioactive atomic nuclei, which are produced through impinging accelerated ion beams on a target. After identifying the ions based on their behaviors, gamma-spectroscopy is performed to measure the radiation emitted during proton and neutron decay from the nucleus's excited states. Radostina's current research is focused on unstable Sc and Ti isotopes with a greater number of neutrons than protons, which were produced and analyzed at Japan's RIKEN Nishina Center. Investigating nuclei far from stability provides insight into the strong nuclear interaction and its behavior, which would not be possible by exploring only stable nuclei.

Aisha_Aqeel_Physikerin.jpg
Aisha has served as a Junior Group Leader since 2022 under the Excellence Initiative of the Munich Centre for Quantum Science and Technology (MCQST), funded by Deutsche Forschungsgemeinschaft (DFG) at the Technical University of Munich, Germany. This year, she will transition to the University of Augsburg to establish her research group, "Spintronics with Helimagnetic Insulators (SpinLEGO)," supported by the Emmy-Noether grant from DFG. Her research focuses on investigating novel magnetic insulators for potential energy-efficient spintronic applications.
Employing crystal growth techniques, Aisha cultivates magnetic materials and subsequently subjects them to characterization through various methods such as magnetometry, x-ray scattering, and magnetic resonance techniques. These materials are then utilized to comprehend fundamental device concepts by harnessing their spin properties. Aisha finds it particularly intriguing to unravel a material's true potential after its growth.
In her previous work, she focused on single-crystal growth and in-depth analysis of spin transport and magnetic resonance properties in chiral magnetic insulators like Cu2OSeO3. In the context of the SpinLEGO project, her goal is to investigate a varied selection of noncollinear magnetic materials, emphasizing achieving ultralow magnetic damping and establishing strong coupling to microwave photons.
In their recent publication, they present the initial experimental investigation employing these novel magnets for applications in artificial intelligence, particularly reservoir computing.

M.Sc. Chloé Gaudu (Wuppertal) - Kalenderwoche 8

Chloe_Gaudu_Physikerin.jpg
Chloe_Gaudu_Physikerin.jpg

Chloé is a Ph.D. student in the Astroparticle physics group at University of Wuppertal, working with hadronic interaction models to solve the “Muon Puzzle.”

Established state-of-the-art models, including EPOS-LHC, Sibyll 2.3d, and QGSJet-II.04, are utilized by astroparticle physicists to describe the hadronic interactions within extensive air showers (EAS) resulting from cosmic ray interactions with Earth's atmosphere. Though developed by separate teams with differing initial assumptions, these models converge on the following consensus: air shower simulations exhibit a muon deficit compared to experimental measurements of the Pierre Auger Observatory — referred to as the “Muon Puzzle.” To solve this puzzle, Chloé works with the Angantyr model of Pythia 8, yet another hadronic interaction model tailored for Large Hadron Collider experiments. Angantyr introduced new features aimed at enhancing descriptions of hadron-nucleus interactions, thus motivating its potential application in air shower studies. The evaluation and validation of this model are done using the analysis framework Rivet, which requires specific plug-ins, of which Chloé has written several for each experimental dataset chosen as a reference. The next steps for her work would be to create a tuned version of Pythia 8 by adjusting parameter values, shifting the physics of Pythia to better describe hadron productions in pion-proton and pion-carbon interactions while keeping intact the knowledge they have gathered so far from proton-proton interactions. This tuned Pythia 8 would be used in codes, like Corsika 8 or MCEq, to probe astroparticle observables, allowing comparison with experimental datasets and previous simulations with the aim of a more accurate description of muon production in EAS.

One should keep in mind that this tuning endeavor is a multi-dimensional task demanding various expertise in the fields of astroparticle and particle physics, from the experimental datasets, model parameters, and observable weight selection for meaningful interpretation, needing a close collaboration between working groups.

The main focus of her research is to track and ideally control in real time the electron dynamics occurring in systems with increasing complexity, from simple molecules to molecules of biological interest and nanostructured materials. To this purpose, her group develops state-of-the-art table-top light sources providing extreme time resolution (from a few femtoseconds down to attoseconds) and spanning from the infrared to the ultraviolet and then further down in wavelengths to the soft-x ray spectral range. In her group, attosecond technology is used to understand the role of electron dynamics in the photo-induced chemical changes that occur in our own biomolecules (e.g., DNA and proteins) in a bottom-up approach. Her research aims to control molecules' chemical reactivity at the electron time scale (attochemistry) to achieve efficient light harvesting. Her approach is fully synergetic, with the possibility to resolve structural changes in molecules through femtosecond time-resolved X-ray diffraction using XUV/X-ray Free Electron Lasers (FELs).

Francesca is active in promoting diversity in science. She has been the Equal Opportunity director for the cluster of excellence AIM and is mentoring female scientists via the DynaMENT mentoring program in Hamburg.
