Be. Taylor et al., STRESS-ENERGY OF A QUANTIZED SCALAR FIELD IN STATIC WORMHOLE SPACETIMES, Physical review. D. Particles and fields, 55(10), 1997, pp. 6116-6122
Static traversable wormhole solutions of the Einstein equations requir
e ''exotic'' matter which violates the weak energy condition. The vacu
um stress-energy of quantized fields has been proposed as the source f
or this matter. Using the Dewitt-Schwinger approximation, analytic exp
ressions for the stress-energy of a quantized massive scalar field are
calculated in five static, spherically symmetric Lorentzian wormhole
spacetimes. We do not attempt to solve the self-consistent semiclassic
al Einstein equations but instead work in the test-field limit. We fin
d that in all five cases, for both minimally and conformally coupled s
calar fields, the stress-energy does not even qualitatively have the p
roperties needed to support the wormhole geometry.
