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…
Semi-classical description of electrostatics and quantization of electric charge
Kolahal Bhattacharya
In this work, we present an explanation of the electric charge quantization based on a semi-classical model of electrostatic fields. We claim that in electrostatics, an electric ch…
A complement to the scalar wave theory of light
Kolahal Bhattacharya
In this paper, we discuss how the concepts of Hamiltonian optics are internally connected to the scalar wave theory of light rays. It is shown that the solutions of the reduced wav…
Unexplored aspects of a variational principle in electrostatics
Kolahal Bhattacharya, Debapriyo Syam
The electrostatic field magnitude can play a role in a variational principle similar to the role of the index of refraction in geometrical optics, allowing the determination of the…
Demystifying the nonlocality problem in Aharonov-Bohm effect
Kolahal Bhattacharya
In this paper, we present a novel semi-classical theory of the electrostatic and magnetostatic fields and explain the nonlocality problem in the context of the Aharonov-Bohm effect…
Can magnetic field be used to reduce cosmic charged particles background to low energy particle detectors?
Kolahal Bhattacharya
The possibility to reduce the background due to cosmic ray charged particles by the use of magnetic field in the ground based low energy particle detectors is explored. The degree…
Supervised learning of photoelectron counting in scintillator-based dark matter experiments
Kolahal Bhattacharya, Christopher Jackson
Many scintillator based detectors employ a set of photomultiplier tubes (PMT) to observe the scintillation light from potential signal and background events. It is important to be…
Analytical computation of process noise matrix in Kalman filter for fitting curved tracks in magnetic field within dense, thick scatterers
Kolahal Bhattacharya, Sudeshna Banerjee, Naba K Mondal
In the context of track fitting problems by a Kalman filter, the appropriate functional forms of the elements of the random process noise matrix are derived for tracking through th…
Error Propagation of the Track Model and Track Fitting Strategy for the Iron CALorimeter Detector in India-based Neutrino Observatory
Kolahal Bhattacharya, Arnab K. Pal, Gobinda Majumder +1
A Kalman filter package has been developed for reconstructing muon () tracks (coming from the neutrino interactions) in ICAL detector. Here, we describe the algorithm of muo…
On the Dependence of Charge Density on Surface Curvature of an Isolated Conductor
Kolahal Bhattacharya
A study of the relation between the electrostatic charge density at a point on a conducting surface and the curvature of the surface (at that point) is presented. Two major scienti…
A Novel Variational Principle in Electrostatics and its Consequences
Kolahal Bhattacharya
We propose a novel variational principle in electrostatics and show that one can derive mirror equation in the context of image problem starting from this principle. The correspond…
Analogy of the grounded conducting sphere image problem with mirror optics
Kolahal Bhattacharya
We show that in the grounded conducting sphere image problem, all the necessary information about the image charge can be found from a mirror equation and a magnification formula.…
