Method to compute the stress-energy tensor for the massless spin 1/2 field in a general static spherically symmetric spacetime [PDF]

, 2002
A method for computing the stress-energy tensor for the quantized, massless, spin 1/2 field in a general static spherically symmetric spacetime is presented. The field can be in a zero temperature state or a non-zero temperature thermal state.
