Quantum geometric signatures of Link-Unlink transitions and nonlinear Hall response in Hopf-link semimetals
Kamalesh Bera, Arijit Saha, Debashree Chowdhury
Quantum geometry, comprising of quantum metric and Berry curvature, plays a significant role in the electronic transport properties of solids. In this work, we theoretically invest…

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…

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…
