"Putting machine learning to the test in a quantum many-body system", Y. Gao, A. Rodriguez, R. A. Römer, appeared on arxiv.org/abs/2602.01981 today, learning multifractality in the bulk of the spectrum.

Submitted just before my August hols driving along the NC500: arxiv.org/abs/2508.01846: theory and experiment agree on our new idea to use compactly-localized states as possible quantum storage devices.
We at Physica E just accepted a great review article by Trambly de Laissardiere et al on "Electronic structure and transport in materials with flat bands: 2D materials and quasicrystals" doi.org/10.1016/j.physe.2025…. Learn about Moire patterns from some of the original discoverers.
Have a look and listen to @warwickuni's new graduation anthem. I must say I find it rather excellent, with meaning in text and music: warwick.ac.uk/insite/news/in…
Have you ever wondered how to generate large-angle convergent-beam electron diffraction patterns via conditional generative adversarial networks? If you have, see our new doi.org/10.1016/j.ultramic.2…. If not, it makes nice pictures as you can see.
So You Want to Be a Physicist? Watch this from Sabine Hossenfelder: youtube.com/watch?v=WR8-Q_UZ…. A largely correct view of what it takes to become a working physicist.

"Phase determination with and without deep learning" in the J1/J2 Ising model in 2D is now out on arxiv.org/abs/2403.09786. We study the performance of unsupervised learning in detecting phase transitions.

Yeah, spot on. Except Hughes looked good even without hair implant.
Can’t help but think that @elonmusk is the 21st century’s Howard Hughes.
Hughes was one of the richest and most influential people of his time, with business interests in aerospace and media.
A man who became known for his eccentric behaviour..
Obsessive. Impossible. Flawed.
Apeared today in EPJB 87, 128 (2024), see doi.org/10.1140/epjb/s10051-…
Our preprint ""Quantum engineering for compactly localized states in disordered Lieb lattices", C. Danieli, J. Liu, R. A. Römer, now available via arxiv.org/abs/2309.04227.
Now "in open-access print" as Shaw, S., & Römer, R. A. (2025). Real-space renormalisation approach to the Chalker–Coddington model revisited: Improved statistics. Physica E: Low-Dimensional Systems and Nanostructures, 165, 116073. doi.org/10.1016/j.physe.2024…
High-precision RG estimates for the critical exponent of the Chalker-Coddington model at 2.51+/-0.11 now within 3% of results from direct approaches, as shown in arxiv.org/abs/2404.00660.
Anderson localization and suppression of surface plasmons in two-dimensional random Au networks, now available at journals.aps.org/prresearch/…
