Metal-insulator transition and intermediate phases in the kagome lattice Hubbard model
Rong-Yang Sun, Zheng Zhu
Motivated by the recent discovery of metallic kagome lattice materials, AVSb (A=K, Rb, Cs), we investigate the ground state of the half-filled kagome lattice Hubbard mo…
Fractional Fermi liquid in a generalized model
Ya-Hui Zhang, Zheng Zhu
Inspired by the recent discovery of superconductivity in the nickelate NdSrNiO, we study a generalized model to investigate the correlated phases induced by d…
Complex Phase Diagram of Doped XXZ Ladder: Localization and Pairing
Rong-Yang Sun, Zheng Zhu, Zheng-Yu Weng
How the ground state nature can be dramatically changed by the distinct underlying spin correlation is a central issue of doped Mott insulators. The two-leg XXZ ladder provides a p…
Magnetic Field Induced Spin Liquids in S=1 Kitaev Honeycomb Model
Zheng Zhu, Zheng-Yu Weng, D. N. Sheng
We investigate the ground state properties of the spin S=1 Kitaev honeycomb model under a magnetic field based on the density matrix renormalization group (DMRG) calculation. With…
Density Wave Instability of Composite Fermi Liquid
Shao-Kai Jian, Zheng Zhu
We investigate the density-wave instability of non-Fermi liquid states by combining exact diagonalization with renormalization group analysis. At the half-filled zeroth Land…
Widely Tunable Quantum Phase Transition from Moore-Read to Composite Fermi Liquid in Bilayer Graphene
Zheng Zhu, D. N. Sheng, Inti Sodemann
We develop a proposal to realise a widely tunable and clean quantum phase transition in bilayer graphene between two paradigmatic fractionalized phases of matter: the Moore-Read fr…
