Poster Session and presentation by Prajakt Pande, Associate Professor, Aarhus University

Speaker: Steffen Schmidt (University of Southern Denmark).Abstract: Symmetry serves as a guiding principle in mathematics and physics. The language of symmetry groups and their actionsorganizes a wide range of phenomena. In this setting, Dirac operators form a natural bridge between quantum mechanics, geometry, and representation theory. In representation theory, Dirac operators provide conceptual and computational tools for addressing basic problems concerning a (semisimple) Lie group: they furnish explicit constructions, give effective criteria for unitarity, contribute to classification results, and relate the topology of locally symmetric spaces to representation-theoretic data. A foundational instance is Parthasarathy's use of a representation-theoretic Dirac operator in the study of discrete series representations. Interest in this circle of ideas intensified in the late 1990s, following Kostant's introduction of the cubic Dirac operator and the subsequent development of \emph{Dirac cohomology}, including Huang–Pandžić’s proofof Vogan's conjecture. In this talk, I present a modern construction of (algebraic) Dirac operators and discuss applications of Dirac operators and Dirac cohomology to representations of Lie superalgebras, including localization principles, relations with Duflo–Serganova cohomology, and character formulas.

The Cake Club is a new and cozy initiative that meets four times each semester with free coffee, cake, and great company.So if you study Data Science, you are invited.Remember to bring your fellow students (lecturers are also welcome).The club meetings are held at the IMADA Forskertorv.You can read more in the Facebook group IMADA-students.

Abdullah Akgül defends her PhD thesis at a public lecture: “Probabilistic Reinforcement Learning for Sample-Efficient Control”.The chairman of the assessment committee, Professor Arthur Zimek, will act as chairman at the defence.The PhD defence takes place in U181 (Ø22-601b-2).All are welcome.

Speaker: Thomas Klein Kvorning (​KTH Royal Institute of Technology). Abstract: Simulating quantum many-body systems is fundamentally challenging because quantum states encode correlations that cannot be decomposed into local parts, leading to an exponential growth of required resources with system size. Yet physical observables are typically local: they are fully determined by density matrices of small subsystems. This raises a central question: can local density matrices be time-evolved without explicitly tracking long-range correlations? In this talk, I address this question using the framework of the information lattice, a scale-resolved decomposition of the information content of a quantum state. This construction provides a precise notion of where information resides in a quantum system, both in space and across length scales, and thereby offers a diagnostic of how correlations build up dynamically. I will show how this perspective reveals regimes in which local degrees of freedom are exactly decoupled from long-range entanglement, as well as how it can guide the development of approximate numerical methods for ab initio simulation of condensed matter systems.

How are SDU students using AI chatbots as personalized learning tools — and how can science teachers guide students towards fruitful and academically appropriate uses?

This year's theme: FROM COGNITION TO CAPACITY Foundations of Empowering KnowledgeThe conference focuses on how empowerment arises through knowledge, and how it is strengthened and supported through interdisciplinary and cross-sectoral collaboration.

Adelina conducted a teaching experiment using figure construction to make student reasoning explicit and support integrative understanding of metabolic pathways.

SDU and NAFA invite you to a webinar where PhD Sizwe Nxasana presents his research on how to support teachers in unlearning old habits and adopting new, more student-centered teaching methods – and on identifying which forms of professional development actually work to make this happen. This presentation offers a unique insight into how project-based learning (PBL) is being adopted and developed in a South African context.At NiSE webinars, Danish science education researchers meet to further develop the science education knowledge ecology.It is about ensuring that everyone both receives knowledge and contributes knowledge and experiences within the pedagogical and scientific work of science education.The NiSE webinars are organized by the STEM Education Research Center – FNUG and the Center of Excellence in Science Education/Naturfagsakademiet (CESE/NAFA). NiSE is the name of the network: Network in STEM Education.This webinar is the second in a series of three during the autumn semester of 2025.Everyone is welcome.

We end the academic year at IMADA with strawberry cake, wine, water, beer, snacks and lots of summer mood 😃!All IMADA students and all staff are invited.No registration needed – just turn up!

CSC2026 is a student-organised symposium that explores the exciting and promising field of computational systems chemistry and cheminformatics - and their applications in research areas such as chemical reaction networks, metabolic pathways, generative models, and analytical chemistry.This free-to-register two day symposium is open to young researchers, ranging from Masters to post-docs, and even industry R&D specialists in the field of computational chemistry wishing to showcase, share, and discuss their work with like-minded researchers in the field. The deadline for registration is: May 15th, 2026Please note: attendees will need to pay for accommodation (if they require it) at a rate of 550 DKK per night - hotel rooms are organised by the team for you!
