Charge-6e superconductivity from doping SU(3) spin liquids
Yan-Qi Wang, Boran Zhou, Hui Yang +1
The paper proposes that doping SU(3)-symmetric spin liquids can generate charge‑6e superconductivity, and it analyzes various SU(3) quantum and chiral spin liquid states to predict…
Quantum Mott semimetal in a one-dimensional Hubbard model
Boran Zhou, Taige Wang, Ya-Hui Zhang
Mott physics in topological bands has recently attracted considerable attention, particularly in the context of twisted bilayer graphene (TBG). However, the essential ingredients f…
Symmetric topological Mott insulator and Mott semimetal
Boran Zhou, Ya-Hui Zhang
Correlated physics in nearly flat topological bands is a central theme in the study of moiré materials. While ground states at integer fillings are typically identified as quantum…
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…
New classes of quantum anomalous Hall crystals in multilayer graphene
Boran Zhou, Ya-Hui Zhang
The recent experimental observation of quantum anomalous Hall (QAH) effects in the rhombohedrally stacked pentalayer graphene has motivated theoretical discussions on the possibili…
Ancilla theory of twisted bilayer graphene I: topological Mott localization and pseudogap metal in twisted bilayer graphene
Jing-Yu Zhao, Boran Zhou, Ya-Hui Zhang
The recent experimental studies of twisted bilayer graphene (TBG) raise a fundamental question: how do we understand Mott localization in a topological band? In this work, we offer…
