DOI: 10.1038/s41467-020-16290-w
Abstract: Topologically nontrivial materials host protected edge states associated with the bulk band inversion through the bulk-edge correspondence. Manipulating such edge states is highly desired for developing new functions and devices practically using their dissipation-less nature… read more here.
