Being well read is a pillar of good science, but the volume of new papers makes it nearly impossible. The python code we used to keep up to date over the years, we’ve now made usable for everyone. Feel free to fork, copy, improve: github.com/zrbyte/paper...

Electron correlation strengthened in multilayer rhombohedral graphite Nature Nanotechnology - Two decades after the exfoliation of graphene, the focus is shifting to ‘reassembling’ graphite to uncover new insights into interacting electrons.

As usual, there are more more questions than answers see the News & Views piece. Rhombohedral graphite is so simple on can consider it a "toy model" for strong correlations, akin to the fruit fly in biology or H atom in quantum mechanics.

Layer-dependent evolution of electronic structures and correlations in rhombohedral multilayer graphene Nature Nanotechnology - By using scanning tunnelling microscopy and spectroscopy, researchers observe layer-dependent electronic correlations in rhombohedral graphene multilayers at 77 K,...

New paper out in Nature Nanotech paper explores how rhombohedral graphite amplifies electron correlations with increasing graphene layers, revealing fingerprints of strong correlations up to a temp of 77 K. Exploring graphite has never been more exciting😀

Curious to see examples when this fails. In the case of experimental data, how can I tell if I'm in the overfitting regime?

Postdoctoral position in atomic-scale stacking control for novel quantum phases in van der Waals materials – Topology in Nanomaterials Research Group About the project:The project focuses on achieving precise control over the atomic stacking order of van der Waals materials, specifically few-layer graphite. We exploit the natural sliding between layers, enabling the construction of artificial crystals with tailored stacking configurations. In the last few years, rhombohedral graphite has gained significant interest, as it hosts strong electronic correlations, exhibiting magnetic insulating states, spin and valley multiferroic orders, and unconventional superconductivity. Building on the group’s expertise in identifying defect-free rhombohedral graphite by electronic Raman scattering, we will combine rhombohedral and hexagonal graphite layers at small twist angles to realize all possible stacking polytypes in few-layer samples. We will then explore their electronic properties through scanning tunneling spectroscopy and low-temperature Raman measurements. This will be the first example of tailoring the defect structure of a macroscopic material at the atomic scale. By gaining full control over the stacking sequence, the project aims to uncover new correlated electron states, offering a platform for advanced quantum materials research.

We are hiring! My group has a postdoc position for two years on experimental aspects of van der Waals material heterostructrues. If you are interested in the cutting edge of topologial, correlated 2D materials research, please apply. More details on our website: www.nemeslab.com/postdoctoral...
