A few minutes before the announcement, let me go with my wish list/prediction for the Nobel Prize in Physics.
First, the prediction
1) Martinis, Devore, Clarke, for the discovery of quantum behaviour of the relative phase in Josephson junctions. This makes superconducting quantum hardware possible.

Check out our paper "One-dimensional CrI3 encapsulated within multi-walled carbon nanotubes", in collaboration with the group of L. Francis at INL and Manuel Valvidares at ALBA. We are reporting the first observation and characterization of a new type of nanostructure, a CrI3 nanotube.
One-dimensional CrI3 encapsulated within multi-walled carbon nanotubes - Communications Chemistry
Producing single-walled inorganic nanotubes is challenging because their multi-walled counterparts are favored during synthesis. Here, the authors produce one-dimensional single-walled CrI3 encapsulat...

It was supposed to be impossible, but a group of researchers say they can generate electricity from Earth's magnetic field. I've had a look.

Spin excitations in nanographene-based antiferromagnetic spin-1/2 Heisenberg chains - Nature Materials
Open-shell nanographenes are used to fabricate length-controlled antiferromagnetic spin-1/2 Heisenberg chains. It is revealed that the spin excitation spectra evolve from gapped to gapless following a...

Can you use (Scanning Tunnel Microscopy) STM to determine the energy dispersion of spin excitations in spin chains? Well, in our latest preprint (arxiv.org/abs/2502.13770) we give the answer: it depends. Some context: excitations in crystals have energy E and momentum, k. 👇

I wish days had 48 hours to be able to catch up with so many exciting things going on in Science these days. This paper got my eye (I was going to say attention, but that would be misleading, check the title):

Is attention all you need to solve the correlated electron problem?
The attention mechanism has transformed artificial intelligence research by its ability to learn relations between objects. In this work, we explore how a many-body wavefunction ansatz constructed fro...
