Dr. Nora Martin (Barcelona) - Kalenderwoche 47
Nora moved to the Centre for Genomic Regulation in Barcelona in July 2023 to lead a team at the Barcelona Collaboratorium for Modelling and Predictive Biology. Previously, she was a doctoral and postdoctoral researcher at Cambridge and Oxford in the UK. Her research is at the physics/biology interface: she uses modeling and theory to elucidate a key component of quantitative models of biological evolution - molecular and phenotypic changes introduced as variation through random mutations. This means modeling the non-linear relationships between genotypes, which are changed through mutations, and higher-order molecular or phenotypic characteristics, which are relevant for selection. She aims to increase the biological realism of these models such that they can be applied to the rapidly increasing amount of available biological data.

M.Sc. Barbara Paetsch (Rehovot, Israel) - Kalenderwoche 45
Barbara is a Ph.D. student in experimental astroparticle physics at the Weizmann Institute of Science in Israel. Her group is part of the XENON collaboration, a collaboration from over 25 institutions across the world searching for dark matter since 2006 with liquid xenon time projection chambers in a series of experiments.
With the latest experiment upgrade XENONnT at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy, they are looking for new physics beyond the standard model, with the primary goal of the direct dark matter detection of weakly interacting massive particles (WIMPs), which are one of the dark matter candidates in our Universe.
But they are also sensitive to other events, such as studying rare weak decay channels like the double electron capture in Xe-124 or the (neutrinoless) double beta decay in Xe-136. Additionally, they are exploring neutrino properties through endeavors like precision measurements of the solar pp neutrino flux, assessments of the solar metallicity via boron-8 neutrinos, and direct measurements of solar CNO neutrinos.
In addition to her work for the XENONnT experiment, Barbara studies liquid xenon scintillation light's temporal and spatial structures with a radiation detection experiment called DireXeno (directional xenon) located at the nuclear research facility, Soreq, in Israel.
The picture was taken in her lab at Weizmann while showing cosmic rays with a small particle detection setup as part of an outreach program.
Update from November 4: Barbara left Israel temporarily due to the war, leaving most of her things behind. She stays with her family in Germany and works as far as possible remotely - Mainly doing data analysis. A significant part of the research in Weizmann, especially lab work, is not happening at the moment, not only because of the frequent rockets but also because approximately a third of students and researchers are currently serving in military operations. Barbara hopes for a soon return to Israel and her research on-site.

Dr. Saša Bajt (Hamburg) - Kalenderwoche 44
Saša heads a group in the Center for Free-Electron Science (CFEL) at DESY (Hamburg) and is also a principal investigator in the Cluster of Excellence (CUI) at the University of Hamburg. She invented new multilayer structures (utilizing interface engineering) that lead to word-record reflectivity Extreme Ultraviolet (EUV) multilayers for EUV Lithography. She is one of the pioneers in XFEL science. Her optics enabled the first coherent diffraction imaging experiments and the first warm dense matter experiment with soft X-ray FEL beam. Saša is currently developing a new generation of X-ray lenses and X-ray microscopes, which will enable multidimensional studies of different materials and biological samples on a nanometer scale. In combination with novel coherent X-ray sources, her multilayer-based X-ray lenses and optical components open up new applications for investigating quantum materials and the architecture of biological cells. Slovenian-born Saša was also honored as an Ambassador of Science, one of the highest national prizes of the Republic of Slovenia, and is an Optica Fellow.

M.Sc. Lena Tarrach (Wuppertal) - Kalenderwoche 42
Lena is a doctoral researcher in the group for theoretical chemical physics at the University of Wuppertal. Her field of research focuses on polymer science, which is situated at the interface between chemistry, physics, and engineering. She currently develops a model that enables the simulation of filled strain-crystallizing elastomer networks on a mesoscopic scale. The aim of her work is to investigate the differences and the interplay of reinforcement by filler and strain-induced crystallization. This model features properties of natural rubber, which is widely used in industrial applications such as tires and, therefore, of high research interest. During her Master's studies, she already specialized in this area and received the prize of VDI Bergischer Bezirksverein for her thesis ''Modelling Study of Reinforcement and Crack Formation in Strain-Crystallizing Elastomer Networks''.

Dr. Nora Linn Strotjohann (Rehovot, Israel) - Kalenderwoche 41
Nora is a Walter Benjamin fellow in the astrophysics group at the Weizmann Institute of Science, where she works as the project scientist of the Large Array Survey Telescope (LAST). LAST is a novel type of telescope that is currently under construction in the Negev desert in the south of Israel. It will consist of 48 off-the-shelf telescopes (32 deployed so far) that monitor the sky to discover transient or variable sources. The combined mirror surface is equivalent to a 1.9m-diameter telescope at a fraction of the cost and with more flexibility due to the modular design.
Besides the hands-on fieldwork, her main research interests are massive stars in the last years before they explode as supernovae. Apparently, nuclear-burning processes in the center of the star sometimes trigger violent outbursts that announce the supernova. She searches for these eruptions and characterizes them with the goal of understanding which processes ultimately lead to the supernova explosion.
Update from October 13: Due to the war with Hamas, Nora has left Israel temporarily. During the last week, the Weizmann Institute and large parts of Israel suffered from regular missile attacks, and most scientists shelter at home. Their observatory appears to be undamaged so far, and they hope to return soon.

Prof. Dr. Anne L'Huillier (Lund, Sweden) - Kalenderwoche 40
Anne is a French/Swedish physicist working on the interaction between short and intense laser fields with atoms at Lund University in Sweden. Her research, which is both experimental and theoretical, is centered around high-order harmonic generation in gases and its applications. In the time domain, these harmonics correspond to a series of extremely short light pulses in the extreme ultraviolet spectral range and with a duration of a few tens or hundreds of attoseconds. Annne's research deals with attosecond source development and optimization as well as with the use of this radiation for the study of ultrafast (electron) dynamics. Attosecond light sources can be designed for various goals, e.g., towards high intensity for nonlinear pump/probe experiments or toward high repetition rate, for applications in condensed matter physics. Another active area of research of Anne and her group is the study of the electron dynamics in atomic systems following a photoionization event induced by absorption of an attosecond light pulse.
In 2023, she became the fifth woman to be awarded the Nobel Prize in Physics. The prize was awarded jointly to Pierre Agostini, Ferenc Krausz, and Anne L’Huillier "for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter."

M.Sc. Lea Kämmerer (Duisburg-Essen) - Kalenderwoche 38
Lea is a Ph.D. student in the group of Heiko Wende at the University of Duisburg-Essen. As a member of the SFB1242, she studies ultrafast non-equilibrium dynamics in condensed matter, with a focus on the investigation of ultrafast dynamics in spin-crossover molecules using time-resolved X-ray absorption spectroscopy.
Spin-crossover molecules have two distinct spin states, a low-spin and a high-spin state, which can be switched between by external stimuli such as light or temperature. Pump-probe experiments such as time-resolved X-ray absorption spectroscopy cannot be performed in a university lab, so she goes to the European XFEL, where extremely intense X-ray pulses are generated, which she needs to get the energy and time resolution to resolve the dynamics in spin-crossover molecules.
The picture was taken in the clean room of the European XFEL, where she successfully mounted the samples for the beamtime.

M.Sc. Verena Feulner (Erlangen) - Kalenderwoche 35
Verena is currently pursuing her Ph.D. in quantum computing at the Chair for Quantum Theory at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) under the supervision of Prof. Michael J. Hartmann. Her current research focuses on superconducting quantum hardware. To process quantum information on larger scales, qubits and their interactions with each other need to be controlled. Verena is working on couplers that can implement interactions between different superconducting qubits. Her current research is on a multi-qubit coupler, where the idea is to couple more than two qubits or pairwise different qubits. During her master’s, which she did in the same group, she also looked at an ansatz for a quantum variational algorithm for a frustrated spin model whose ground state in larger systems cannot be calculated with classical methods.

Jun. Prof. Dr. Jana Günther (Wuppertal) - Kalenderwoche 32
Jana is an assistant professor (Juniorprofessorin) at the Bergische Universität Wuppertal. Her research focuses on studying the QCD phase diagram using lattice gauge theory methods. In particular, she is concerned with the behavior of QCD matter at finite densities, which is a particular challenge for lattice QCD calculations. Here, the notorious "sign problem" prevents the use of the established Monte Carlo simulations, which is why new methods are sought, or extrapolations are used to solve QCD in this domain. The knowledge gained in this way can be used to understand heavy ion collisions at particle accelerators and theoretically explain the results obtained there from first principles. To reproduce the experimental conditions in lattice QCD simulations, she uses the method of analytical continuation from imaginary chemical potential.

Dr. Kathrin Aziz-Lange (Oberkochen) - Kalenderwoche 31
Kathrin is Head of Coating and Surface Roughness Metrology at ZEISS Semiconductor Manufacturing Technology in Oberkochen, Germany. The department of around 80 scientists and engineers focuses on the development of metrology processes that enable high-precision measurements of optical components for the extreme ultraviolet (EUV) lithography optics manufactured by ZEISS. These optical systems are later integrated into microchip manufacturing machines. The accuracy specifications of these systems range into sub-nanometer dimensions and are often beyond everything that can be found on the market. Therefore, they also pose great challenges for the development of the metrology machines and processes for their components concerning precision, size, and reliability. The spectrum of methods in Kathrin’s responsibility covers, amongst others, atomic force microscopy, interferometry, defect detection, and EUV-reflectometry and allows, e.g., to prove surface roughness down to sub-nanometers.
Before joining ZEISS, Kathrin held a Junior professorship at Bielefeld University and was a Helmholtz Young Investigator group leader, focusing on solar fuel research.

Dr. Meike Küßner (Bochum) - Kalenderwoche 30
Meike is a post-doc at Ruhr-Universität Bochum. She searches for hints of exotic hadrons in the experimental data from the BESIII experiment. Understanding how exotic hadrons are formed contributes to the fundamental understanding of mass generation in strong interaction. By interpreting the analyzed data using highly sophisticated partial wave analysis techniques, Meike contributed to the interpretation of light hybrids and glueball candidates. Besides being involved in data analyses, she is working on building up the forward electromagnetic calorimeter of the future PANDA experiment. The PANDA experiment will use proton–antiproton annihilation events from the future FAIR accelerator facility at GSI Darmstadt to study strong interaction physics at medium energy, including hadron spectroscopy, search for exotic hadrons, hadrons in media, nucleon structure, and exotic nuclei.

Dr. Anjana Ashok (Hannover) - Kalenderwoche 28
Anjana is a recent Ph.D. and now a Postdoctoral Fellow at the Max Planck Institute for Gravitational Physics, Hannover. She searches for elusive, continuous gravitational wave signals in the data from Advanced-LIGO detectors. Continuous gravitational waves are expected from rotating neutron stars owing to a non-axisymmetry in their mass distribution. Electromagnetic observations of neutron stars as pulsars provide valuable information about the object. Using this information, Anjana predicts the shape of the gravitational wave signal generated by the neutron star and carries out a ‘targeted’ search for the signal, employing an approach that binds multiple messengers from the neutron star. Starting next year, she will work on pulsar timing arrays, where pulsars and gravitational waves are involved in a story different from the one in her Ph.D. research.

Dr. Chiara Lindner (Freiburg) - Kalenderwoche 27
Chiara is a scientist researching novel techniques for spectroscopy at the Fraunhofer Institute for Physical Measurement Techniques in Freiburg.
Her research focuses on using entangled photon pairs for sensitive high-resolution mid-infrared spectroscopy. The idea is to use a correlated pair of one mid-infrared (for sample interaction) and one near-infrared photon (for highly sensitive detection) and transfer the information between them using quantum interference effects. As Chiara and her colleagues found out, the quantum interferometer can be operated in close analogy to a classical Fourier-transform spectrometer, which greatly improves the spectral resolution and measurement accuracy.
For her Ph.D. studies, Chiara has received the Quantum Futur Award (1st place), awarded by the BMBF, and the Hugo-Geiger Preis (2nd place) awarded by the Freistaat Bayern and the Fraunhofer Gesellschaft.

Dipl.-Phys. Leli Schiestl (Berlin) - Kalenderwoche 17
Leli works remotely as a Data Engineer at Mozilla. Data engineers' job is to make data usable for data analysts. That includes finding relevant data, bringing the raw data in a useful format, and then automating that process for constantly updating data. Each new dataset is a new puzzle to solve, understanding how it has been generated, what questions can be answered with it - and equally or more important, what questions can not be answered with the current data.
In her free time, Leli is a member of "feminismus und computer kram," an online hackspace for women, non-binary and trans folks, and loves to put LEDs on everything.

Prof. Dr. Marina Gerhard (Marburg) - Kalenderwoche 13
Marina has held a tenure track position (W1) at the physics faculty at the Philipps-University Marburg since 2021. Her research interests focus on the optical properties of organic and hybrid semiconductors. Molecular materials are very versatile building blocks for organic electronic devices, and the flexibility of this material class can be even further enhanced in heterostructures. To understand the processes emerging after the absorption of light, e.g., photocurrent generation in an organic solar cell, it is important to comprehend the photoexcitation dynamics in time-resolved experiments. Marina’s junior research group is specialized in time-resolved photoluminescence spectroscopy combined with spatially resolved experiments. With this framework of techniques, it is possible to gain insight into the fate of bound electron-hole pairs. These so-called excitons are the primary photoexcited species in organic semiconductors. A part of the group’s research is embedded in the CRC 1083 “Structure and Dynamics at internal interfaces”.

M.Sc. Celina Hellmich (Braunschweig) - Kalenderwoche 11
Celina is a Ph.D. student at the TU Braunschweig and is currently a member of the working groups Nanostructuring and Microsystems Technology at PTB. There she contributes to the further development of high-precision measurement methods of 3D microscopes.
To measure accurately and with high precision with a microscope, it must first be calibrated with so-called standards. But in 3D microscopy, it is not only necessary to calibrate the lateral and height scales but also the calibration of the flatness error of coordinate planes and the shear of coordinate axes. 3D standards meet these requirements. However, currently used 3D standards are manufactured with focused ion beams. Each standard is, therefore, a cost-intensive custom-made product that also requires time-consuming calibration. Celina and her colleagues are developing a wafer-based mask process to produce 3D standards. This way, many structures can be reproducibly produced and adapted to calibrate the respective device.

Dr. Elena Redaelli (Garchign/Munich) - Kalenderwoche 8
Elena is a Minerva group leader at the Max Planck Institute for Extraterrestrial Physics in Garching (Munich). Since she was a child, she has been deeply fascinated by the night sky, but she also enjoyed chemistry. When, during her master's studies, she discovered the astrophysics branch of astrochemistry, it was love at first sight. Elena’s work aims at understanding how stars and planetary systems are born, using molecules as a probe to investigate the chemistry and physics of star-forming regions. The main targets of her research are the densest and coldest phases of the interstellar medium in the Milky Way, where protostars are about to form. In order to detect the faint emissions from different molecular species, she uses radio telescopes, such as the IRAM 30m antenna in Sierra Nevada, Spain, shown in the picture.

M.Sc. Christina Möller (Göttingen) - Kalenderwoche 1
Christina is currently writing up her Ph.D. work on ultrafast magnetism with extreme ultraviolet light in the group of Prof. Stefan Mathias at the University of Göttingen. Light with such short wavelengths (~ 20 nm) has many advantages for the investigation of different elements in complex magnetic materials, but it takes some effort to generate this light in the first step. This combination of laser and solid-state physics on the ultrafast timescale is what Christina enjoys the most. Her research paves the way to gain a microscopic understanding of the magnetic behavior after an optical excitation with a femtosecond laser pulse - a question that is still puzzling many researchers in the field.
