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…
Transport signatures of Bogoliubov Fermi surfaces in normal metal/time-reversal symmetry broken -wave superconductor junctions
Amartya Pal, Arijit Saha, Paramita Dutta
In recent times, Bogoliubov Fermi surfaces (BFSs) in superconductors (SCs) have drawn significant attention due to a substantial population of Bogoliubov quasiparticles (BQPs) toge…
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 $…
Time evolution of Majorana corner modes in Floquet second-order topological superconductor
Arnob Kumar Ghosh, Tanay Nag, Arijit Saha
We propose a practically feasible time-periodic sinusoidal drive protocol in onsite mass term to generate the two-dimensional~(2D) Floquet second-order topological superconductor,…
Topological characterization and stability of Floquet Majorana modes in Rashba nanowire
Debashish Mondal, Arnob Kumar Ghosh, Tanay Nag +1
We theoretically investigate a practically realizable Floquet topological superconductor model, based on a one-dimensional Rashba nanowire and proximity induced -wave supercondu…
