摘要：
We compute the graviton one-loop contribution to a classical energy in a traversable wormhole background. Such a contribution is evaluated by means of a variational approach with Gaussian trial wavefunctionals. A zeta function regularization is involved to handle divergences. A renormalization procedure is introduced and the finite one-loop energy is considered as a self-consistent source for the traversable wormhole.
