Spin-orbit coupling driven topological superconductivity in twisted bilayer graphene-WSe heterostructures
Kamalesh Bera, Arijit Saha, Tanay Nag
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…

Non-Hermitian band topology in twisted bilayer graphene aligned with hexagonal boron nitride
Kamalesh Bera, Debasish Mondal, Arijit Saha +1
Utilizing the established Bistritzer-MacDonald model for twisted bilayer graphene (tBLG), we theoretically investigate the non-Hermitian (NH) topological properties of this in the…

Thermoelectric properties of magic angle twisted bilayer graphene-superconductor hetero-junction: effect of valley polarization and trigonal warping
Kamalesh Bera, Pritam Chatterjee, Priyanka Mohan +1
We theoretically investigate the thermoelectric properties (electronic contribution) of a normal-superconductor (NS) hybrid junction, where the normal region consists of magic-angl…
