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_{3}=…
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…
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…
Dirac and chiral spin liquids on spin-1/2 square-lattice Heisenberg antiferromagnet
Hui-Ke Jin, Hong-Hao Tu, Ya-Hui Zhang
We revisit the challenging problem of identifying the quantum spin liquid candidate in the spin-1/2 - Heisenberg antiferromagnet on the square lattice. By integrating the…
