Magnetic Breakdown and Anomalous Quantum Oscillation in Rhombohedral Tetralayer Graphene
Jing-Yu Zhao, Yang-Zhi Chou, Sankar Das Sarma
The paper studies how magnetic breakdown near Van Hove singularities in electron‑doped rhombohedral tetralayer graphene leads to unusual quantum oscillation patterns, offering a pr…
Yamaji effect in models of underdoped cuprates
Jing-Yu Zhao, Shubhayu Chatterjee, Subir Sachdev +1
Recent angle-dependent magnetoresistance measurements in underdoped cuprates have revealed compelling evidence for small hole pockets in the pseudogap regime, including observation…
Minimal loop currents in doped Mott insulators
Can Cui, Jing-Yu Zhao, Zheng-Yu Weng
For the - model, variational wave functions can generally be constructed based on an accurate description of antiferromagnetism (AFM) at half-filling and an exact phase-strin…
Resonating-valence-bond superconductor from small Fermi surface in twisted bilayer graphene
Jing-Yu Zhao, Ya-Hui Zhang
Mechanism of superconductivity in twisted bilayer graphene (TBG) remains one of the central problems in correlated moiré materials. The most intriguing question is about the natur…
Integration of imprint-free and low coercivity ferroelectric BaTiO3 thin films on silicon
Jingtian Zhao, Beatriz Noheda, Martin F. Sarott
Highly-crystalline ferroelectric oxides integrated on Si hold great promise for energy-efficient memory and logic technologies. Exploiting epitaxial strain engineering in these mat…
Mixed valence Mott insulator and composite excitation in twisted bilayer graphene
Jing-Yu Zhao, Boran Zhou, Ya-Hui Zhang
Interplay of strong correlation and flat topological band has been a central problem in moiré systems such as the magic angle twisted bilayer graphene (TBG). Recent studies show t…
