Wide-angle photo of a university lecture hall with tiered seating filled with students, looking down toward a professor standing at the front beside a desk and a projected slide. The slide discusses generative modeling and renormalization group flows. Large windows line the left wall, and a balcony with speakers runs above the classroom. A blue banner at the bottom of the image contains text about an exciting presentation by Prof. Jan Pawlowski at a STRUCTURES Jour Fixe event, with a clapping emoji.

How can renormalization group flows be used to encode & learn physical information? This was the focus of an exciting Jour Fixe today, presented by Prof. Jan Pawlowski 👏.

Events like this are a great opportunity for our community to connect and discuss about AI developments with concrete problems in physics and chemistry. This was made possible thanks to financial support by the STRUCTURES Cluster of Excellence at Heidelberg University. 3/3

This workshop brought together around 50 researchers to discuss modern applications of AI across many areas of physics, through advanced lectures and research seminars. Topics ranged from data-driven modelling to new computational tools for tackling complex physical systems. 2/3

Earlier this November, our YRC member Luis Itza Vazquez-Salazar gave a talk on molecular simulations with and without machine learning at the Scientific AI for Physics Workshop at Instituto Principia in São Paulo, Brazil. 1/3

Simon’s participation, like that of our other YRC members at similar international events, was made possible thanks to financial support by the STRUCTURES Cluster of Excellence at Heidelberg University – fostering collaborations, new ideas, and continued scientific exchange. 3/3

The two-week school, aimed at Master’s and PhD students, focused on how complex quantum systems evolve in and out of equilibrium. 2/3

From November 03 to 14, Simon Böhly took part in the II School on Emergent Phenomena in Non-Equilibrium Quantum Many-Body Systems at ICTP-SAIFR/IFT-UNESP in São Paulo, Brazil, where he gave a presentation on “Probing universal relaxation speed in a Bose–Einstein condensate far from equilibrium.” 1/3

We regret to inform you that this week’s Jour Fixe has been cancelled.

However, the STRUCTURES Get-Together is still taking place, and we hope to see many of you there!

#STRUCTURESHeidelberg #AcademicEvents #uniheidelberg #JourFixe

This STRUCTURES Jour Fixe will be about quantum gravity! We welcome Astrid Eichhorn (Heidelberg University) for a talk on “Quantum gravity – from fundamental questions to observational probes.” When and where: Tomorrow 5 December at 13:30 in Philosophenweg 12 gHS.

Abstract: What is the quantum structure of spacetime? To answer this question, we need a quantum theory of gravity. In this talk, I will explain the key ideas underlying several different approaches to quantum gravity. In a second part, I will discuss how quantum gravity could affect black-hole spacetimes and how quantum gravity theories connect to modified gravity theories, in which black holes beyond General Relativity are often investigated.

We are happy to announce this week’s Jour Fixe!!

Astrid Eichhorn will talk about “The Nonlinear Universe – Asymptotic Approaches to Cosmic Structures.”

The work by X. Chen, E. Dizer, E.R. Rodríguez & R. Schmidt shows that the impurity's recoil creates an energy gap, stabilizing the quasiparticle behaviour. For the first time, a unified theory captures both regimes – bridging the well-defined polaron with a strongly disrupted quantum state. (3/3)

A single impurity in a quantum gas can behave like a new kind of particle: a Fermi polaron. Theory predicted that such quasiparticles should break down in the limit of a heavy, immobile impurity (the Anderson orthogonality catastrophe). (2/3)

⚡ A favorite among participants: the lightning sessions, offering early-career researchers a stage to share ideas and connect.

The event was organized by Anna Wienhard, Freya Jensen, Levin Maier, Diaaeldin Taha, and Michael Bleher. (4/4)

🤝 Jointly organized by Max-Planck-Institut für Mathematik in den Naturwissenschaften and STRUCTURES Cluster of Excellence Heidelberg, the workshop featured inspiring keynote talks, expert presentations, and contributions from industry partners like DeepMind, Deepshore, and Isomorphic Labs. (3/4)

With 132 participants, it was the first event of this scale to unite the research communities across all three fields – building bridges and allowing for new collaboration between areas that have traditionally developed independently. (2/4)
