Valence-bonds, spin liquids and unconventional criticality in a 1D Kondo insulator
Nai Chao Hu, Rui-Zhen Huang, Nick Bultinck
We consider a one-dimensional multi-orbital Kondo lattice model and show that by tuning the kinetic energy of the itinerant electrons it is possible to stabilize Kondo insulators w…
Disentangling critical quantum spin chains with Clifford circuits
Chaohui Fan, Xiangjian Qian, Hua-Chen Zhang +3
Clifford circuits can be utilized to disentangle quantum states with polynomial cost, thanks to the Gottesman-Knill theorem. Based on this idea, the Clifford circuits augmented mat…
Fractional Chern insulator candidate in twisted bilayer checkboard lattice
Jia-Zheng Ma, Rui-Zhen Huang, Guo-Yi Zhu +2
We investigate a fractional Chern insulator (FCI) candidate arising from Moiré bands with higher Chern number C=2 on a magic angle twisted bilayer checkboard lattice (MATBCB). The…
Measuring the Boundary Gapless State and Criticality via Disorder Operator
Zenan Liu, Rui-Zhen Huang, Yan-Cheng Wang +2
The disorder operator is often designed to reveal the conformal field theory information in quantum many-body systems. By using large-scale quantum Monte Carlo simulation, we study…
Relevant long-range interaction of the entanglement Hamiltonian emerges from a short-range gapped system
Chuhao Li, Rui-Zhen Huang, Yi-Ming Ding +3
Beyond the Li-Haldane-Poilblanc conjecture, we find the entanglement Hamiltonian (EH) is actually not closely similar to the original Hamiltonian on the virtual edge. Unexpectedly,…
