Imaging Interacting Two-Dimensional Anisotropic Electrons
Ziyu Xiang, Jianghan Xiao, Hongyuan Li +9
We directly visualize a two-dimensional anisotropic Wigner crystal and its quantum melting in monolayer 1T-ReSe2 using non-invasive scanning tunnelling microscopy. In crystals with…
Visualizing the Impact of Quenched Disorder on 2D Electron Wigner Solids
Zhehao Ge, Conor Smith, Zehao He +17
Electron Wigner solids (WSs)1-12 provide an ideal system for understanding the competing effects of electron-electron and electron-disorder interactions, a central unsolved problem…
A Materials Foundation Model via Hybrid Invariant-Equivariant Architectures
Keqiang Yan, Montgomery Bohde, Andrii Kryvenko +10
Machine learning interatomic potentials (MLIPs) can predict energy, force, and stress of materials and enable a wide range of downstream discovery tasks. A key design choice in MLI…
Imaging Tunable Luttinger Liquid Systems in van der Waals Heterostructures
Hongyuan Li, Ziyu Xiang, Tianle Wang +16
One-dimensional (1D) interacting electrons are often described as a Luttinger liquid1-4 having properties that are intrinsically different from Fermi liquids in higher dimensions5,…
