摘要

In this work, we find exact wormhole solutions in the context of noncommutative geometry, and furtherexplore their physical properties and characteristics. The energy density of these wormhole geometries isa smeared and particle-like gravitational source, where the mass is diffused throughout a region of lineardimension α~(1/2)due to the intrinsic uncertainty encoded in coordinate commutator. Furthermore, wealso analyze these wormhole geometries considering that the equation governing quantum fluctuationsbehaves as a backreaction equation. In particular, the energy density of the graviton one loop contributionto a classical energy in a traversable wormhole background and the finite one loop energy density isconsidered as a self-consistent source for these wormhole geometries. Interesting solutions are foundfor an appropriate range of the parameters, validating the perturbative computation introduced in thissemi-classical approach.
