"Spatiotemporal aspects of Turing patterns"
Streszczenie:Biological patterns such as stripes, spots, and digit arrangements often emerge through Turing’s reaction–diffusion mechanism, where gene regulatory networks interact with protein-mediated signaling across cells. This framework explains how local gene activity can produce large-scale organization during development. Yet, the nonlinear nature of reaction–diffusion equations makes it difficult to answer key questions with simulations alone. Can different networks give rise to the same pattern? Which patterns are most likely under parameter changes? How robust are they to noise or initial conditions, and how quickly do they form? We address these challenges by deriving analytical formulas in the linear and weakly nonlinear regimes. These formulas provide explicit predictions about pattern likelihood, robustness, and dynamics. Comparisons with numerical simulations of established models confirm their validity, offering new insights into the inverse problem of inferring regulatory mechanisms from observed biological patterns.

"Applications of shielded ultracold molecules: Formation of ultracold complexes and quantum magnetism
⇒ link to meeting"
Streszczenie:Ultracold polar molecules can be shielded against loss inside an optical trap using an external static electric or a microwave field. Shielded ultracold molecules have opened the doors to exploring new physics. For example, enhanced stability in the traps has enabled the realization of Bose-Einstein condensates and Fermi-degenerate samples of polar molecules. The external field, which enables shielding, also enables tuning the interaction by allowing us to control the sign and magnitude of the s-wave scattering length a. Furthermore, a can be tuned such that near-threshold bound states appear. These weakly bound states are called field-linked (FL) tetramer states. In our recent work, we have proposed a Stimulated Raman Adiabatic Passage (STIRAP) mechanism to transfer weakly bound FL tetramers to deeper bound states [1]. We consider static-electric-field shielded alkali diatomic molecules initially in their ground electronic state. We identify an excited electronic state for achieving the STIRAP transfer and propose proof-of-principle experiments.
In another recent work, we showed that shielded ultracold molecules allow quantum magnetism with SU(N) symmetry, where N can be as high as 32 [2]. This is unlike the case with atoms, with which SU(N) magnetism has been realized with N up to 10. In addition, SU(N) magnetism with shielded molecules can have both attractive and repulsive interactions. In conclusion, I would show in my talk how ultracold molecules provide exciting new opportunities, from creating polyatomic molecules to quantum magnetism.

"Hyperpolarized Xenon-129 MRI technology: Advancements and the road towards multimodal imaging with PET/MRI"
Streszczenie:Hyperpolarized 129Xe MRI enables up to 100,000-fold signal enhancement, providing unique functional insights into lung and brain physiology. Dr Mitchell Albert’s group pioneered the first in vivo HP 129Xe brain imaging, revealing perfusion abnormalities in stroke and Alzheimer’s disease. Recent developments include rapid TOF perfusion mapping and multi-slice HP 129Xe imaging, greatly improving spatial resolution and repeatability. The team is now advancing a dedicated PET/MRI insert to integrate functional xenon MRI with molecular PET for next-generation multimodal neuroimaging

"AFM-assisted nanoengineering of layered surfaces: The case of controlled nano-manipulation and cutting of molybdenum disulfide"
Streszczenie:I will review our ongoing work on scan-induced assembly of gold islands on MoS2 surfaces and nanocutting of the same surfaces using diamond tips. The deposition of Au atoms on MoS2 leads to triangular islands aligning with the surface lattice of MoS2. The Au islands can be easily manipulated along the zigzag crystallographic directions of MoS2. As a result, the islands tend to form jagged nanostrips several µm-long. On flat (multilayer) MoS2 the strips are compact, but this is not the case for Au islands manipulated on few-layer MoS2. With regard to MoS2 nanocutting, we observed periodic exfoliation of MoS2 nanochips under loading forces just above the fracture resistance. Cutting along armchair directions produces less exfoliation and less wear than the zigzag directions. We also observed interesting avalanche effects in the stick-slip motion of the cutting tool, and supported this finding with dedicated MD simulations. These results highlight the potential of scanning probe microscopy in the microengineering of layered materials and underscore the need for a deeper understanding of the underlying physical mechanisms to develop useful manipulation and lithography protocols.

"Recent Gravitational-Wave Observations from the LIGO–Virgo–KAGRA Collaboration"
Streszczenie:Gravitational waves, predicted over a century ago by Einstein’s theory of General Relativity, have become a powerful observational tool for probing the Universe. In this talk, I will briefly introduce the physical nature of gravitational waves and the interferometric methods used to detect them. I will then discuss the current status and capabilities of the operating detectors—LIGO, Virgo, and KAGRA—as well as planned upgrades and proposals for next-generation observatories. The main part of the presentation will focus on the scientific results from the recently completed fourth observation run (O4), highlighting key astrophysical discoveries and their implications for gravitational-wave astronomy. I will conclude by outlining the contributions of the Polgraw group within the Virgo Collaboration, emphasizing our role in data analysis and detector development.
