In general, the stress energy tensor is the flux of momentum p^\mu over the surface x^\nu . It is a machine that contains a knowledge of 10 Oct 2007 We continue looking at the energy-momentum tensor (the four-dimensional extension of stress tensors), first establishing the usual Remark: Used in Minkowski spacetime; For some fields, like the Klein-Gordon field, it agrees with the stress-energy tensor, but more generally it may not be The quantum stress-energy tensor and its intricate relationship with spacetime geometry.

Here we shall only discuss general relativistic diffeomorphism-invariant matter theories in a curved spacetime in the classical limit $\hbar\to 0$ for simplicity. In particular, we will not discuss the SEM pseudotensor for the gravitational field, but only the stress-energy-momentum (SEM) tensor for matter (m) fields $\Phi^A$. Symmetric Stress-Energy Tensor We noticed that Noether’s conserved currents are arbitrary up to the addition of a divergence-less field. Exploiting this freedom the canonical stress-energy tensor Θµν can be modified to a new tensor Tµν such that ∂ µ Tµν=0 and dxT dxn M n nnM 00νν= Θ (hereMn denotes the spatial sub-manifold of the The stress energy tensor, redu ced to a perfect fluid, we can better understand the stress energy tensor of general relativity: in fact, it consists mainly in its matrix under pressure and energy Existing of different variants of the pressure field stress-energy tensor shows the absence of any unambiguous definition of this tensor. Besides the 4-velocity, density and pressure, this tensor often includes a function with specified properties so that the tensor could describe the energy and stress in the substance. Stress Energy Tensor Simple Examples and Geometric Consequences, a Schur Theorem Notational conventions.

However, the traces of the stress-energy tensors describing different kinds of stress-energy will not all be the same. For example, the trace of the stress-energy tensor describing electromagnetic radiation is zero; but the trace of the stress-energy tensor describing dust is nonzero.

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 $U=(E^2+B^2)/8\pi k$ and momentum density $\vec{S}=(\vec{E}\times\vec{B})/4\pi k$ (in units where $c=1$, with $k$ being the Coulomb constant). From a physical perspective, the stress-energy tensor is the source term for Einstein's equation, kind of like the electric charge and current is the source term for Maxwell's equations. It represents the amounts of energy, momentum, pressure, and stress in the space. The stress–energy tensor is defined as the tensor T αβ of order two that gives the flux of the αth component of the momentum vector across a surface with constant x β coordinate. In the theory of relativity, this momentum vector is taken as the four-momentum.
