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,…
Quantum Melting of a Disordered Wigner Solid
Ziyu Xiang, Hongyuan Li, Jianghan Xiao +15
The behavior of two-dimensional electron gas (2DEG) in extreme coupling limits are reasonably well-understood, but our understanding of intermediate region remains limited. Strongl…
Wigner Molecular Crystals from Multi-electron Moiré Artificial Atoms
Hongyuan Li, Ziyu Xiang, Aidan P. Reddy +10
Semiconductor moiré superlattices provide a versatile platform to engineer new quantum solids composed of artificial atoms on moiré sites. Previous studies have mostly focused on t…
Imaging Moiré Excited States with Photocurrent Tunneling Microscopy
Hongyuan Li, Ziyu Xiang, Mit H. Naik +12
Moiré superlattices provide a highly tunable and versatile platform to explore novel quantum phases and exotic excited states ranging from correlated insulators1-17 to moiré excito…
Mapping Charge Excitations in Generalized Wigner Crystals
Hongyuan Li, Ziyu Xiang, Emma Regan +9
Transition metal dichalcogenide-based moire superlattices exhibit very strong electron-electron correlations, thus giving rise to strongly correlated quantum phenomena such as gene…
