Phys. Rev. D 67, 124020 (2003) [23 pages]Semiclassical wormholesReceived 3 February 2003; published 19 June 2003 Smooth-throat wormholes are treated as possessing quantum fluctuation energy with a scalar massive field as its source. The heat kernel coefficients of the Laplace operator are calculated in the background of the arbitrary-profile throat wormhole with the help of the zeta-function approach. Two specific profiles are considered. Some arguments are given that wormholes may exist. It serves as a solution of semiclassical Einstein equations in the range of specific values of the length, a certain radius of the wormhole’s throat, and a constant of nonminimal connection. © 2003 The American Physical Society URL:
