Kinematics of Acceleration-Induced Excitations in Confined Quantum Fields
Hemansh Shah, Sanved Kolekar
We investigate quantum field excitations in a rigid cavity that undergoes a transition from inertial motion to uniform acceleration while maintaining constant proper length. By con…

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…
