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…

So (2, 1) algebra, local Fermi velocity, and position-dependent mass Dirac equation
Bijan Bagchi, Rahul Ghosh, Christiane Quesne
We investigate the (1+1)-dimensional position-dependent mass Dirac equation within the confines of so(2,1) potential algebra by utilizing the character of a spatial varying Fermi v…

Non-hermitian Dirac Hamiltonian in the presence of local Fermi velocity
Rahul Ghosh
We present a new approach to study a class of non-Hermitian (1+1)-dimensional Dirac Hamiltonian in the presence of local Fermi velocity. We apply the well known Nikiforov-Uvarov me…
