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…
Second-order topological superconductor via noncollinear magnetic texture
Pritam Chatterjee, Arnob Kumar Ghosh, Ashis K. Nandy +1
We put forth a theoretical framework for engineering a two-dimensional (2D) second-order topological superconductor (SOTSC) by utilizing a heterostructure: incorporating noncolline…
Engineering anomalous Floquet Majorana modes and their time evolution in helical Shiba chain
Debashish Mondal, Arnob Kumar Ghosh, Tanay Nag +1
We theoretically explore the Floquet generation of Majorana end modes~(MEMs) (both regular - and anomalous -modes) implementing a periodic sinusoidal modulation in chemical p…
Topological Superconductivity by Engineering Noncollinear Magnetism in Magnet/ Superconductor Heterostructures: A Realistic Prescription for 2D Kitaev Model
Pritam Chatterjee, Sayan Banik, Sandip Bera +4
We report on a realistic and rather general scheme where noncollinear magnetic textures proximitized with the most common -wave superconductor can appear as the alternative to $…
