Speaker: Sara Maggio (​University of Bonn).Abstract: Feynman integrals associated with geometries beyond the Riemann sphere, such as elliptic and Calabi–Yau geometries, are playing an increasingly important role in modern precision calculations. They appear not only in collider cross sections, but also in gravitational-wave scattering. A powerful way to compute these integrals is through systems of differential equations, particularly when these can be brought into canonical form, making their singularity structure manifest. In this talk, I will present a method to construct canonical differential equations for multi-loop Feynman integrals beyond the polylogarithmic setting, with particular emphasis on Calabi–Yau examples. After introducing the method through the two-loop sunrise integral, I will show how it applies to the cutting-edge case of the three-loop multi-parameter banana integrals.

Speaker: David Jordan (​University of Edinburgh).Skein modules are vector spaces attached to closed 3-manifolds and reductive groups G, which capture the calculus of line operators in Chern-Simons theory.  A few years ago we showed with Gunningham and Safronov that skein modules are finite-dimensional when the quantum parameter q is generic.  In this talk I will give a overview of recent progress since then:  I will survey the known formulas for 3-manifolds, I will explain finiteness for 3-manifolds with boundary, and with embedded line defects, and I'll also explain a new kind of finiteness result for skein categories.

Speaker: Ondrej Hulik (Heidelberg University).Abstract: TBA

Speaker: Matthew Yu (University of Oxford)Abstract: I will explain a comprehensive framework for characterizing the infrared (IR) phases of a fermionic QFTs in (3+1)d, based on their quantum anomalies associated with a finite symmetry. We uncover a fundamental dichotomy among these anomalies: the first class of anomalies can always be realized by symmetric gapped states, while the second class can never be realized by gapped states without breaking the given symmetry, establishing the phenomenon of symmetry-enforced gaplessness in these settings. Using the construction of symmetry extension afforded to us by new developments in fusion 2-categories, we construct the candidate gapped states that theories with the first class of anomalies can flow to in the IR. As an application, I will provide examples of concrete predictions for the candidate IR phases of (3+1)d gauge theories based on our results.

In this event we will look at how teaching can help spark students’ individual learning awareness and build engagement to help foster a strong learning community between our students.

Curious about how Team-Based Learning (TBL) works in large classes? You now have the opportunity to visit SUND and observe TBL in practice.

Speaker: Daniel Stack (Atom Computing)Abstract: This talk will describe recent progress on neutral-atom-based quantum computation at Atom Computing Inc. These results are enabled by a flexible platform capable of large qubit numbers, high-fidelity gates, arbitrary qubit connectivity, and mid-circuit measurement. I will describe how these features can enable circuits with large numbers of physical and logical qubits. I will also present recent demonstrations of techniques for reusing and replenishing qubits after mid-circuit measurement—key steps for enabling the execution of long error-correcting computation despite atom loss.

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

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).
