Amazing photofinish. But even more amazing: the bending of the spokes is independent of the speed of the bike. The curves have a free parameter θ (the angle of the spoke at the time of the finish) and given by y(x)=(1+x)tan(θ+x) for all x for which -2 ≤ x ≤ 0 and 0 ≤ (1+x)/cos(θ+x) ≤ 1

Glad to see our paper "Perfect particle transmission throughduality defects" published in Nature Physics: rdcu.be/fysBS Do all weird effects in quantum field theory have to do with entanglement?

On the origin of finite entanglement scaling

Symmetric mass generation of interacting chiral fermions on a one-dimensional lattice without fermion doubling
Symmetric mass generation is the interaction-induced opening of a fermion gap without spontaneous symmetry breaking. The anomaly-free 3-4-5-0 model of Wang and Wen provides a minimal one-dimensional s...

An uncomfortable fact is that it is impossible to write down a translationally invariant Hamiltonian for a lattice many-body system in a classical and constant magnetic field. Infinite PEPS with gauge tensors can counteract this magnetic translation symmetry: arxiv.org/abs/2604.24574

Although 2025 was absolutely shocking in terms of the cruelty of powerful people, science can still be a refuge from it. A highlight for me was retreating to the mountains to teach at the Les Houches Summer School. Here are my lecture notes: arxiv.org/abs/2512.24390

Tensor networks provide a powerful new framework for classifying and simulating correlated and topological phases of quantum matter. Their central premise is that strongly correlated matter can only b...

Philip Anderson, more than any other physicist, helped pivot theoretical physics away from reductionism toward emergence as a guiding principle. Yet almost no popular-science books explore this crucial shift—an exception is www.panmacmillan.com/authors/fran... . An excerpt:

Frank Verstraete @fverstraete.bsky.social · 16/10/2025
What if all the laws that we know are just effective laws, valid at certain length scales? Isn't that emergence? And does that not mean that reductionism is impossible, as we will never be able to know the real laws that lie at the origin of this flow?

The 2025 Nobel Prize in Physics, awarded for macroscopic quantum mechanical tunneling, is a perfect example of emergent phenomena in action. It’s also one of the key reasons we wrote our book www.panmacmillan.com/authors/fran... — because no other popular science book talks about this.

Finally, a book that does justice to the hidden heroes of #quantum physics: Landau, Anderson, Wilson i.e., cond. mat. physics community. Symmetry breaking & renormalization, concepts which unite #physics. It includes key papers from many-body physics (see timeline). Looking forward to reading it!!

Happy to see our book "Why Nobody Understands Quantum Physics" published in English www.panmacmillan.com/authors/fran.... Unlike other popular science books, we explain quantum and its applications in the way working physicists use and understand them, without shying away from the many-body problem.
