Color superconductors and holon metals from doping a Fractional Chern insulator
Ya-Hui Zhang
We develop a unified framework for metallic and superconducting phases obtained by doping a fractional Chern insulator (FCI) with . Starting from the parton construction $c(…
Pseudogap and Non-Fermi-liquid criticality in double Kondo model for bilayer nickelates
Jing-Yu Zhao, Ya-Hui Zhang
Motivated by recent experimental progress on high-temperature superconductivity in bilayer nickelates, we investigate the phase diagram of the normal state in a bilayer Kondo latti…
Holon metal, charge-density-wave and chiral superconductor from doping fractional Chern insulator and SU(3) chiral spin liquid
Ya-Hui Zhang
Recent experiments have observed superconductivity proximate to the nu = -2/3 fractional quantum anomalous Hall (FQAH) insulator in twisted MoTe2. A critical open question is wheth…
Charge-4 Anyon Superconductor from Doping chiral spin liquid
Lu Zhang, Ya-Hui Zhang, Xue-Yang Song
Previous studies have shown that chiral spin liquid can emerge in the SU() Hubbard model on triangular lattice. A natural question then arises: What is the phas…
Anyon superfluid in trilayer quantum Hall systems
Taige Wang, Ya-Hui Zhang
Intertwining intrinsic topological order with gapless collective modes remains a central challenge in many-body physics. We show that a quantum-Hall trilayer at $ν_{1}=ν_{2}=ν_{…
Continuous transition from Fermi liquid to A fractional Chern insulator
Ya-Hui Zhang
Recent experiments in moiré materials have observed fractional Chern insulators (FCI) at zero magnetic field, providing an opportunity to study the transition from FCI to the more…
