Charge-6e superconductivity from doping SU(3) spin liquids
Yan-Qi Wang, Boran Zhou, Hui Yang +1
We propose doping -symmetric spin liquids as a route toward charge- superconductivity. This generalizes the idea of constructing charge- superconductivity from doped…
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 th…
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…
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…
Variational wavefunction for Mott insulator at finite using ancilla qubits
Boran Zhou, Hui-Ke Jin, Ya-Hui Zhang
The Mott regime with finite offers a promising platform for exploring novel phases of matter, such as quantum spin liquids (QSL) that exhibit fractionalization and emergent gau…
Interplay of electronic crystals with integer and fractional Chern insulators in moiré pentalayer graphene
Dacen Waters, Anna Okounkova, Ruiheng Su +8
The rapid development of moiré quantum matter has recently led to the remarkable discovery of the fractional quantum anomalous Hall effect, and sparked predictions of other novel c…
Topological electronic crystals in twisted bilayer-trilayer graphene
Ruiheng Su, Dacen Waters, Boran Zhou +5
In a dilute two-dimensional electron gas, Coulomb interactions can stabilize the formation of a Wigner crystal. Although Wigner crystals are topologically trivial, it has been pred…
Type II t-J model in charge transfer regime in bilayer LaNiO and trilayer LaNiO
Hanbit Oh, Boran Zhou, Ya-Hui Zhang
Recent observations of an 80 K superconductor in LaNiO under high pressure have attracted significant attention. Recent experiments indicate that LaNiO may…
Fractional quantum anomalous Hall effects in rhombohedral multilayer graphene in the moiréless limit and in Coulomb imprinted superlattice
Boran Zhou, Hui Yang, Ya-Hui Zhang
The standard theoretical framework for fractional quantum anomalous Hall effect (FQAH) assumes an isolated flat Chern band in the single particle level. In this paper we challenges…
