An exact approach to frustrated total internal reflection and Goos-Hänchen shift for s-polarised light
Sayanho Biswas, Kolahal Bhattacharya
An exact analogy between wave mechanics in quantum theory and the scalar wave treatment of optics emerges from the marriage of Newtonian formulation of geometrical optics [1] and t…

Pedagogical study of the image of a magnetic dipole in front of a superconducting sphere
Hemansh Alkesh Shah, Kolahal Bhattacharya
The method of images to solve certain electrostatic boundary-value problems is taught worldwide in undergraduate-level physics courses. Though it is also possible to employ this te…

Semi-classical understanding of flux quantization in superconductors
Kolahal Bhattacharya
Like electric charge, magnetic flux is also quantised. Theoretically, one can show that the flux quantum must be h/e, as observed in the quantum Hall effect. However, in the superc…
