Novel wormholes are obtained in Einstein-scalar-Gauss-Bonnet theory for several coupling functions. The wormholes may feature a single-throat or a double-throat geometry and do not demand any exotic matter. The scalar field may asymptotically vanish or be finite, and it may possess radial excitations. The domain of existence is fully mapped out for several forms of the coupling function.

  1. New exact traversable wormhole solution to the Einstein-scalar-Gauss-Bonnet Equations coupled to a power-Maxwell electrodynamics

    gr-qc 2019-08 conditional novelty 7.0 of 10

    A two-parameter exact traversable wormhole solution is constructed in Einstein-scalar-Gauss-Bonnet theory with power-Maxwell electrodynamics, recovering the Ellis wormhole when the electric charge vanishes.

  2. Wormhole solutions in generalized Rastall gravity

    gr-qc 2024-12 reject novelty 4.0 of 10

    Static spherical wormhole solutions are constructed in generalized Rastall gravity with linear equations of state, and are claimed to satisfy energy conditions without exotic matter.
