Combined spontaneous symmetry-breaking and symmetry-protected topological order from cluster charge interaction
Chen Peng, Rong-Qiang He, Yuan-Yao He +1
The study of symmetry-protected topological states in presence of electron correlations has recently aroused great interest as rich and exotic phenomena can emerge. Here, we report…

Correlation Effects in Quadrupole Insulators: a Quantum Monte Carlo Study
Chen Peng, Rong-Qiang He, Zhong-Yi Lu
The quadrupole insulator, a high-order topological insulator, with on-site Hubbard interaction is numerically studied by large-scale projector quantum Monte Carlo (PQMC) simulation…
