Large scale neural quantum states reveal the interplay between superconductivity and quantum criticality in the Hofstadter-Hubbard model

Christopher Roth, Andrew Millis, Tomohiro Soejima

Understanding how a parent insulating state shapes the superconductivity that emerges upon doping is a long-standing problem dating back to Anderson's resonating-valence-bond propo…

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…

Chiral Spin Liquid and Quantum Phase Transition in the Triangular Lattice Hofstadter-Hubbard Model

Stefan Divic, Tomohiro Soejima, Valentin Crépel +2

Recent advances in moiré engineering motivate the study of lattice models of strongly-correlated electrons subjected to substantial orbital magnetic flux. We analyze the triangula…

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…

-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…

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…
