On the Natural Equivalence Between Canonical and Hilbert Energy Momentum Tensors via Noether's Theorem
Peir-Ru Wang
In this work, we investigate the structure and properties of the canonical energy momentum tensor (EMT) across a range of field theories. We begin by developing a unified and syste…

Canonical Energy-Momentum Tensor of Abelian Fields
Peir-Ru Wang, Yen-Cheng Chang
In this tutorial, we provide the natural derivation of symmetrical, gauge-invariant canonical energy-momentum tensor for the abelian gauge field, i.e., the electromagnetic field.
