Generation of higher-order topological insulators using periodic driving
Arnob Kumar Ghosh, Tanay Nag, Arijit Saha
Topological insulators~(TIs) are a new class of materials that resemble ordinary band insulators in terms of a bulk band gap but exhibit protected metallic states on their boundari…
Floquet second-order topological Anderson insulator hosting corner localized modes
Arnob Kumar Ghosh, Tanay Nag, Arijit Saha
The presence of random disorder in a metallic system accounts for the localization of extended states in general. On the contrary, the presence of disorder can induce topological p…
