WebMar 5, 2024 · The electromagnetic field has a stress-energy tensor associated with it. From our study of electromagnetism we know that the electromagnetic field has energy density U = (E2 + B2) / 8πk and momentum density →S = (→E × →B) / 4πk (in units where c = 1, with k being the Coulomb constant). This fixes the components of the stress … WebThe canonical stress-energy tensor is Θµν µ λ νλ µν π =− −∂η 1 4 FA (3.14) From the spin-matrices (2.15b), we find the Belinfante tensor for the vector field as: BFAαµν αµ ν π =− 1 4.
