Quantum Monte Carlo study of topological phases on a spin analogue of Benalcazar-Bernevig-Hughes model
Jiaojiao Guo, Junsong Sun, Xingchuan Zhu +3
We study the higher-order topological spin phases based on a spin analogue of Benalcazar-Bernevig-Hughes model in two dimensions using large-scale quantum Monte Carlo simulations.…

Electronic band gaps and transport properties in aperiodic bilayer graphene superlattices of Thue-Morse sequence
Changan Li, Hemeng Cheng, Ruofan Chen +4
We investigate electronic band structure and transport properties in bilayer graphene superlattices of Thue-Morse sequence. It is interesting to find that the zero- gap ce…
