NOETHER’S THEOREM - TRACELESS STRESS-ENERGY …
IDEALS @ Illinois: Improvement of Stress -Energy Tensor The improved stress-energy tensor defines the same field energy-momentum and angular momentum as the conventional tensor, and it is traceless for a non-interacting field theory when all coupling constants are physically dimensionless.

The matrix \(T\) is called the stress-energy tensor, and it is an object of central importance in relativity. (The reason for the odd name will become more clear in a moment.) In general relativity, it is the source of gravitational fields. The stress-energy tensor is related to physical measurements as follows.

a new positive energy theorem for general relativity. In the field theory, the energy is given by E = R hTtti, and so as in the general discussion above, one is considering states for which the expectation value of a particular operator, i.e., the stress-energy tensor, is nonvanishing.
