We calculate the Casimir energy-momentum tensor induced in a scalar field by a macroscopic ultrastatic spherically symmetric long-throated traversable wormhole, and examine whether this exotic matter is sufficient to stabilize the wormhole itself. The Casimir energy-momentum tensor is obtained (within the $\mathbb{R}\ifmmode\times\else\texttimes\fi{}{S}_{2}$ throat) by a mode sum approach, using a sharp energy cutoff and the Abel-Plana formula; Lorentz invariance is then restored by use of a… Expand
