Dr. Maria Azhar (Duisburg-Essen) - Kalenderwoche 26
Maria is a postdoctoral researcher at the Faculty of Physics at the University of Duisburg-Essen. She has a nanoscience and physics background and a PhD from the University of Groningen in the Netherlands. Her research is centered on the theoretical study of topological magnetic textures or “knots” in the continuous magnetic field in matter. These include complex structures such as spin spirals, skyrmions, hopfions, and dislocation lines. Maria employs a combination of analytical techniques and numerical simulations to study the stability and properties of these magnetic textures. Recently she predicted a new topological defect in the magnetic texture -- a “screw dislocation.”
Such magnetic textures are significant because they provide deeper insights into fundamental physics questions related to topology, symmetry, and conservation laws. Moreover, they have practical applications with the potential to revolutionize the current paradigm of 2-bit magnetic data storage devices, potentially leading to major advancements in current computation technology.
Beyond her research, Maria enjoys teaching at the university and is an active member of the academic community. She frequently collaborates with other researchers, both experimentalists and theoreticians and engages in the organization of scientific conferences.

Dr. Lisa-Marie Kern (Berlin) - Kalenderwoche 24
Lisa is a postdoctoral researcher at the Max Born Institute (MBI) for Nonlinear Optics and Short Pulse Spectroscopy in Berlin. She combines nanofabrication, laser technology, and x-ray imaging to investigate complex spin textures in magnetic thin films.
She studied Physics in Germany and France: she went to Nancy, Luxembourg, and Saarbrücken for her bachelor's degree, before moving to Berlin and Paris for her master's studies.
During her PhD studies at MBI, Lisa worked on the manipulation of chiral magnetic quasiparticles, so-called skyrmions. She developed an approach that allows controlling the positions of individual skyrmions with a few nanometers' precision. For example, the control achieved has led to the guided motion of nanometer-scale skyrmions over micrometer distances, which may become relevant for spintronic applications. In addition, Lisa's experiments to image such spin textures in real-time provided new fundamental insights into their dynamics upon ultrafast stimuli.
Lisa was recently awarded the Carl Ramsauer Prize 2023 of the Berlin Physical Society and the Dissertation Prize 2024 of the Condensed Matter Section (SKM) of the German Physical Society (DPG).

Dr. Claudia Merger (Trieste, Italy) - Kalenderwoche 21
Claudia recently joined the Theory of Neural Networks group at the Scuola Internazionale Superiore di Studi Avanzati (SISSA) in Trieste, Italy, as a postdoc after obtaining her PhD degree at RWTH Aachen University and Forschungszentrum Jülich. She works on neural networks, such as modern image and text generators whose success stems from an intrinsic, condensed representation of the statistics of the data used to train them. Conventionally, this representation does not lend itself to a direct interpretation. Claudia decodes these representations by translating them into a physical language, namely interactions between the different degrees of freedom that make up new data, such as pixels, in the case of image generation. In doing so, she obtains an interpretable new interacting theory of the data and can also study if different types of neural networks are biased towards specific representations. Thus, she works at the crossroads between explainable artificial intelligence (AI) and inference - she believes that by explaining what neural networks (the central objects of modern AI) have learned, we can obtain a better understanding of the problems they solve and simultaneously improve their reliability and efficiency.

Dr. Larissa Boie (Villigen, Switzerland) - Kalenderwoche 18
Larissa is an experimental physicist at the Paul Scherrer Institute in Villigen, Switzerland. She currently conducts research in the field of laser-based advanced manufacturing. With very short pulses and small laser spot sizes, they can use IR light to modify a transparent material locally via multi-photon absorption processes. This can lead to new functionalities at the surface of glasses, such as photoconducting properties. With synchrotron radiation from the Swiss Light Source, they investigate how a femtosecond laser transforms parts of a metallic glass into a crystalline phase in operando conditions to understand the role of different laser parameters. She is also planning and conducting ultrafast optical experiments in a laser lab, investigating how fast the lasers change the internal arrangement of the atoms in the glass. The work on advanced manufacturing processes combines her interest in both x-rays at large research facilities and the freedom to work on her own setup in a laser lab, building on her expertise in ultrafast dynamics from her Ph.D. research. With their results, they hope to find mechanisms that allow them to do laser-writing in three dimensions in transparent glasses, which can be useful in building novel types of chips and other miniature devices.

Dr. Laura Olivera-Nieto (Heidelberg) - Kalenderwoche 17
Laura is a postdoc at the Max-Planck-Institut für Kernphysik in Heidelberg after recently completing my Ph.D. at the same institute. She is a gamma-ray astrophysicist, using observations of the sky in the TeV energy band to study the places in the universe that accelerate particles. Her research is currently focused on microquasars, a special type of stellar binary system hosting a black hole pulling off matter from its companion. As a result, oppositely directed beams of plasma ("jets") are produced. Similar relativistic jets are also observed emanating from the centers of active galaxies, although with much larger sizes. Using data taken with the H.E.S.S. observatory, she studies microquasars inside our Galaxy in order to characterize where and through which mechanisms are particles accelerated to energies above hundreds of TeV in these systems.
On the more experimental side, she developed a novel method for background rejection that uses the central telescope as a "muon veto," improving the high energy sensitivity of H.E.S.S., and she contributes to the Southern Wide-field Gamma-ray Observatory (S.W.G.O.), a proposal for a new gamma-ray observatory in the Southern Hemisphere. Additionally, she is one of the lead developers of the Very-High-Energy Open Data Format. This community initiative aims to provide the field of astroparticle physics with a shared, open-source data standard that ensures the FAIR principles and facilitates data-sharing and reproducibility.

Dr. Aisha Aqeel (Munich) - Kalenderwoche 12
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
Chloé is a Ph.D. student in the Astroparticle physics group at the 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.

Prof Dr. Francesca Calegari (Hamburg) - Kalenderwoche 5
Francesca leads the Attosecond Science group at the Center for Free-Electron Laser Science at DESY in Hamburg and is a full professor of physics at Hamburg University. She is also the head of the scientific board of PIER, the strategic partnership between DESY and Hamburg University, and one of the speakers of the Cluster of Excellence “Advanced Imaging of Matter.” Amongst other distinctions, she is an ERC StG laureate, received the ICO prize and the Ernst Abbe medal from the International Commission of Optics, and is an Optica Fellow.
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.
