Dirac equation in curved spacetime: the role of local Fermi velocity

B. Bagchi, A. Gallerati, R. Ghosh

We study the motion of charge carriers in curved Dirac materials, in the presence of a local Fermi velocity. An explicit parameterization of the latter emerging quantity for a nano…

Refractive index profiles for a -symmetric optical structure

Bijan Bagchi, Rahul Ghosh, Sauvik Sen

By mapping the scalar Helmholtz equation (SHE) to the Schrodinger form we investigate the behaviour of optical structure when the refractive index distribution a…
