I'm curious what is the interpretation of spatial components of stress-energy
tensor in case of Klein-Gordon field or electromagnetic field. Time-time component
is the energy density of the field, time-spatial components are the momentum density.
The diagonal spatial components are probably preassures in different spatial direction
(but what is the preassure of field?).
Thanks for help.
