Partial lattice defects in higher order topological insulators
Raquel Queiroz, Ion Cosma Fulga, Nurit Avraham +2
Nonzero weak topological indices are thought to be a necessary condition to bind a single helical mode to lattice dislocations. In this work we show that higher-order topological i…

Splitting the hinge mode of higher-order topological insulators
Raquel Queiroz, Ady Stern
The surface of a higher order topological insulator (HOTI) comprises a two-dimensional topological insulator (TI) with broken inversion symmetry, whose mass is determined by the mi…
