Gauge-invariant optical selection rules for excitons
Tharindu Fernando
Presently, the optical selection rules for excitons under circularly-polarized light are manifestly gauge-dependent. Recently, Fernando et al. introduced a gauge-invariant, quantiz…

Observation of flat and weakly dispersing bands in a van der Waals semiconductor Nb3Br8 with breathing kagome lattice
Sabin Regmi, Anup Pradhan Sakhya, Tharindu Fernando +15
Niobium halides, Nb3X8 (X = Cl,Br,I), which are predicted two-dimensional magnets, have recently gotten attention due to their breathing kagome geometry. Here, we have studied the…

A Quantized Interband Topological Index in Two-Dimensional Systems
Tharindu Fernando, Ting Cao
We introduce a novel gauge-invariant, quantized interband index in two-dimensional (2D) multiband systems. It provides a bulk topological classification of a submanifold of paramet…
