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…

Artificial Hawking radiation, weak pseudo-Hermiticity and Weyl semimetal blackhole analogy
Bijan Bagchi, Sauvik Sen
We examine the possibility of artificial Hawking radiation by proposing a non-PT-symmetric weakly pseudo-Hermitian two-band model containing a tilting parameter by pursuing Weyl se…

MOND and asymptotic safe gravity
Bijan Bagchi, Sauvik Sen
The modified Newtonian dynamics (MOND) paradigm is discussed in the context of asymptotic safe gravity. We estimate quantum correction to the logarithmic potential which is well kn…
