Commencing from the low-energy Bistritzer-MacDonald continuum model of twisted bi-layer graphene (tBLG) with proximity-induced Ising, Rashba, and intrinsic spin-orbit couplings (SO…
Chiral topological superconductivity in twisted bilayer and double bilayer graphene
Kamalesh Bera, Tanay Nag, Arijit Saha
We present a theoretical investigation of the emergence of chiral topological superconductivity in small-angle twisted bilayer graphene (tBLG) and twisted double bilayer graphene (…
Generation and time evolution of anomalous Floquet Majorana flat edge modes in two-dimensional noncolinear magnet-superconductor heterostructures
Kamalesh Bera, Priyanka Mohan, Arijit Saha
We theoretically investigate the realization of gapless Floquet topological superconducting phases in a two-dimensional magnet-superconductor heterostructure (2D Shiba lattice) in…
Josephson current signature of Floquet Majorana and topological accidental zero modes in altermagnet heterostructures
Amartya Pal, Debashish Mondal, Tanay Nag +1
We theoretically investigate the generation and Josephson current signatures of Floquet Majorana end modes (FMEMs) in a periodically driven altermagnet (AM) heterostructure. Consid…
