    Spin Density and Non-symmetric Stress-Energy Tensor

    For a review with many references, check out: Hammond 2002 Rep. Prog. Phys. 65 599. There is a section on the experimental consequences of torsion.

    Asymmetric stress tensor gives asymmetric stress-energy tensor?

    Actually, the energy momentum tensor (EMT) does not have to be symmetric. If the metric tensor is not symmetric then neither is the EMT. Einstein tried to relate the non-symmetric part to the electromagnetic field, but this never panned out. Recently it has been shown that the antisymmetric part...

    Spin Density and Non-symmetric Stress-Energy Tensor

    If the metric tensor is not symmetric then the energy momentum tensor is not symmetric, and so, we have the physical interpretaion that the antisymmetric part of the metric tensor is related to spin. In fact, it is the potential of the spin field (torsion). The mathematics is given in...
