Wannier Topology and Quadrupole Moments for a generalized Benalcazar-Bernevig-Hughes Model
Liu Yang, Alessandro Principi, Niels R. Walet
We analyze a special separable and chiral-symmetric model with a quantized quadrupole moment, extending the Benalcazar-Bernevig-Hughes model [Science 357, 61 (2017)]. Using nested-…
