Energy-momentum tensor from diffeomorphism invariance in classical electrodynamics
Taeseung Choi
We reexamine the energy-momentum tensor in classical electrodynamics from the perspective of spacetime-dependent translations, i.e., diffeomorphism invariance in flat spacetime. Wh…

Probability Density in Relativistic Quantum Mechanics
Taeseung Choi, Yeong Deok Han
In the realm of relativistic quantum mechanics, we address a fundamental question: Which one, between the Dirac or the Foldy-Wouthuysen density, accurately provide a probability de…
