Our new paper is out on the ArXiv!
arxiv.org/abs/2508.20939
Using electromagnetism as example, we describe how boundaries in gauge theories give rise to edge modes and quantum reference frames for boundary/large gauge transformations.

Last week, a group of 75 young researchers from all over the world came to York for the EMS-IAMP Spring School: Symmetry and Measurement in Quantum Field Theory. It was an absolute pleasure to organize this event.
#paperalert
Read here our paper published in CMP on how quantum reference frames can be used in the description of measurements on symmetric backgrounds and the relation to recent results on type reduction of algebras of observables in QFT.

I do love me a cocktail 🍸
On a train back to York and suddenly there’s snow everywhere ☃️
This is what motivates me to this day, by doing rigorous mathematics you can extend your intuition for what is possible in physics and at the same time be very precise.
What I especially loved was the fact that, using relatively simple math, one can make this theory which many would describe as abstract or counterintuitive very concrete.
As long as I can remember I loved watching science documentaries or read (children’s) books on science. When I was ~14 I read a book on special relativity explained using simple geometry (Very Special Relativity by Sander Bais) which really got me interested in theoretical physics.
As long as he stays of from Bluesky the problem can’t be that serious
In a slight existential crisis again because should I use bluesky for making contact with other scientists or post about gay shenanigans. I don’t suppose bluesky has the option to make private alts yet 🤔
Definitely need to plan my next visit to @kcl.ac.uk on a sunny day for an even better view
On my way to London to pick up my passport and attend the LGBTQIA+ STEM Day event at the Royal Institute by @prideinstem.bsky.social, who am I seeing there?
Happy LGBTQIA+ STEM Day everyone!
🚨 Deadline Approaching: 10 December 2024! 🗓
LGBTQ STEM Berlin is looking for new volunteers to join our Core Team!
If teamwork and leadership are your vibe, we’re the perfect fit for you! 🌈

Of course incompleteness theorems are very closely related to non-computability etc
So I am reminded of incompleteness theorems: no matter how many things you assume, one can always construct statements that you cannot prove. I wonder if something similar holds here: no matter how many functions one introduces, one can always construct equations without closed form solutions 🤔
On the other hand, perhaps it is a good thing that the universe is not just described by some closed form expressions cause that would be rather boring.
I usually happily avoid statistics in my work, but of course optimisation (in terms of extremising action functionals) plays an important role in theoretical physics. Here the extrema are given as solutions to PDE’s, which in many (even linear) cases also lack closed form solutions.
I happen to be in London on Monday, so I’ll be dropping by ^^
Will there be some organised socialising (networking sounds a bit too serious) before or after the talks?
Well yeah I admit my work is a bit far away from real world applications, mathematical foundations of quantum field theory etc., but technically I’m in an applied maths cluster so what is and isn’t applied is just a matter of perspective I suppose
Thanks, when I looked on there a while ago it seemed like it was mostly the typical social media ‘math’ puzzles, but that may have just been bad timing. I’ll keep an eye on it!
I sort of need it myself unfortunately 🙃
Are there any more mathsy people around on this app? I’m a mathematical physicist myself and would be nice to find some skeeps with similar academic interests 🧪 #math #science #stem
Hadn’t been very active on ‘that other app’ for a while now, but it feels good to be back in a place where the sky is blue
I’m interested, queer math phys postdoc here
Het Physgal, not sure if this feed is more for applied/experimental or theoretical physics, but I’m a mathematical physicist working on foundations of quantum field theory
