Effects of Disorder On Thouless Pumping In Higher-Order Topological Insulators
Congwei Lu, Zhao-Fan Cai, Haibo Wang +2
We investigate the effects of random onsite disorder on higher-order Thouless pumping of noninteracting fermionic Benalcazar-Bernevig-Hughes (BBH) model. The interplay of disorderi…

Topological quantum transition driven by charge-phonon coupling in higher-order topological insulators
Congwei Lu, Mei Zhang, Haibo Wang +2
We investigate a second-order topological quantum transition of a modified Kane-Mele model driven by electron-phonon interaction. The results show that the system parameters of the…
