Robust electro-mechanical actuation in hydrogenated Xenes leading to reversible topological transition
Sujith Nedungattil Subrahmanian, Nabendu Mondal, Joydeep Bhattacharjee
We report from first principles, the possibility of reversible onset of topological insulator(TI) phase in heavier hydrogenated Xenes (Xane), namely, germanane and stanane, exclusi…

Partitioning of total charge in matter from geometric phases of electrons
Joyeta Saha, Sujith Nedungattil Subrahmanian, Joydeep Bhattacharjee
Based on geometric phases of Bloch electrons computed from first-principles, we propose a scheme for unambiguous partitioning of charge in matter, derivable directly from the Kohn-…
