A new matrix representation of the Maxwell equations based on the Riemann-Silberstein-Weber vector for a linear inhomogeneous medium
Sameen Ahmed Khan, Ramaswamy Jagannathan
We derive a new eight dimensional matrix representation of the Maxwell equations for a linear homogeneous medium and extend it to the case of a linear inhomogneous medium. This der…
Quantum mechanics of round magnetic electron lenses with Glaser and power law models of
Sameen Ahmed Khan, Ramaswamy Jagannathan
Scalar theory of quantum electron beam optics, at the single-particle level, derived from the Dirac equation using a Foldy-Wouthuysen-like transformation technique is considered. R…
Quantum mechanics of bending of a nonrelativistic charged particle beam by a dipole magnet
Sameen Ahmed Khan, Ramaswamy Jagannathan
Quantum mechanics of bending of a nonrelativistic monoenergetic charged particle beam by a dipole magnet is studied in the paraxial approximation. The transfer map for the position…
On the deformed oscillator and the deformed derivative associated with the Tsallis q-exponential
Ramaswamy Jagannathan, Sameen Ahmed Khan
The Tsallis -exponential function is found to be associated with the deformed oscillator defined by the relations $\left[N,a^\dagger\right]…
A Statistical Approach to Prime Gaps and Andrica's Conjecture
Sameen Ahmed Khan
We examine the prime gaps using a statistical approach. It is first shown that the Andrica's conjecture is true for half or more cases. Using the arguments of averages, it is furth…
Coordinate Geometric Generalization of the Spherometer and Cylindrometer
Sameen Ahmed Khan
Spherometer is an instrument widely used for measuring the radius of curvature of a spherical surface. Cylindrometer is a modified spherometer, which can measure the radii of both…
