Quantum Geometry Driven Crystallization: A Neural-Network Variational Monte Carlo Study
Agnes Valenti, Yaar Vituri, Yubo Yang +7
Wigner crystals are a paradigmatic form of interaction driven electronic order. A key open question is how Berry curvature and, more generally, quantum geometry reshape crystalliza…
Beyond the Lowest Landau Level: Unlocking More Robust Fractional States Using Flat Chern Bands with Higher Vortexability
Yitong Zhang, Siddhartha Sarkar, Xiaohan Wan +3
Enhancing the many-body gap of a fractional state is crucial for realizing robust fractional excitations. For fractional Chern insulators, existing studies suggest that making flat…
hBN alignment orientation controls moiré strength in rhombohedral graphene
Matan Uzan, Weifeng Zhi, Matan Bocarsly +11
Rhombohedral multilayer graphene hosts a rich landscape of correlated symmetry-broken phases, driven by strong interactions from its flat band edges. Aligning to hexagonal boron ni…
Topological constraint on crystalline current
Tomohiro Soejima, Junkai Dong, Ophelia Evelyn Sommer +2
How much current does a sliding electron crystal carry? The answer to this simple question has important implications for the dynamic properties of the crystal, such as the frequen…
Phonons in Electron Crystals with Berry Curvature
Junkai Dong, Ophelia Evelyn Sommer, Tomohiro Soejima +2
Recent advances in 2D materials featuring nonzero Berry curvature have inspired extensions of the Wigner crystallization paradigm. This paper derives a low-energy effective theory…
-Jellium Model for the Anomalous Hall Crystal
Tomohiro Soejima, Junkai Dong, Ashvin Vishwanath +1
The jellium model is a paradigmatic problem in condensed matter physics, exhibiting a phase transition between metallic and Wigner crystal phases. However, its vanishing Berry curv…
