High Chern Number Quantum Anomalous Hall States in Haldane-Graphene Multilayers
Yuejiu Zhao, Long Zhang, Fu-Chun Zhang
We consider a rhombohedral-stacked -layer graphene coupled to a monolayer of Haldane model. We show that high order Dirac points in multilayer graphene can be gapped out by topo…
Spinons, solitons and random singlets in the spin-chain compound copper benzoate
Ying Chen, Guijing Duan, Yuejiu Zhao +15
The antiferromagnetic Heisenberg chain is a paradigmatic quantum system hosting exotic excitations such as spinons and solitons, and forming random singlet state in the pre…
Topology-ferrimagnetism intertwining via weak interactions in Lieb lattices
Lei Chen, Bei-Bei Wang, Jianmin Yuan +3
A common wisdom about quantum many-body systems is that emergent phases typically fall into either the Landau-Ginzburg paradigm or topological classifications. Experimentally reali…
Spectroscopic Feature of Quantum Many-Body Scar States
Wenjie Wei, Long Zhang
We study the dynamical correlations of nonintegrable systems with quantum many-body scar (QMBS) states generated by a ladder operator. The spectral function of the ladder operator…
