Traversable Finslerian wormholes supported by phantom energy
Frontiers in Physics, 2023 This paper supplements the article (Eur. Phys. J. C 76: 246, 2016) by extending some more new wormhole solutions in the background of Finslerian geometry.

Ellis wormholes in anti-de Sitter space
European Physical Journal C: Particles and Fields, 2021 We construct traversable wormholes with anti-de Sitter asymptotics supported by a phantom field. These wormholes are massless and symmetric with respect to reflection of the radial coordinate $$\eta \rightarrow - \eta $$ η → - η .

Black Hole and Wormhole Solutions in Einstein–Maxwell Scalar Theory
Universe, 2022 We classified and studied the charged black hole and wormhole solutions in the Einstein–Maxwell system in the presence of a massless, real scalar field.

Wormholes from heavy operator statistics in AdS/CFT [PDF]
Journal of High Energy Physics, 2022 We construct higher dimensional Euclidean AdS wormhole solutions that reproduce the statistical description of the correlation functions of an ensemble of heavy CFT operators.

Closed Timelike Curves, Singularities and Causality: A Survey from Gödel to Chronological Protection
Universe, 2021 I give a historical survey of the discussions about the existence of closed timelike curves in general relativistic models of the universe, opening the physical possibility of time travel in the past, as first recognized by K.

Axion wormholes with massive dilaton [PDF]
Classical and quantum gravity, 2022 If Euclidean wormholes contribute meaningfully to the path integral of quantum gravity they can have important implications for particle physics and cosmology.

Nuclear Physics B, 2009 We obtain a large class of smooth Lorentzian p-brane wormholes in supergravities in various dimensions. They connect two asymptotically flat spacetimes. In cases where there is no dilaton involved in the solution, the wormhole can connect an AdS_n\times S^m in one asymptotic region to a flat spacetime in the other. We obtain explicit examples for (n,m)=

Unimodular gravity traversable wormholes [PDF]
The European Physical Journal Plus, 2022 Wormholes are outstanding solutions of Einstein’s General Relativity. They were worked out in the late 1980s by Morris and Thorne, who have figured out a recipe that wormholes must obey in order to be traversable, that is, safely crossed by travelers.

Traversable Wormholes in Einstein-Dirac-Maxwell Theory. [PDF]
Physical Review Letters, 2020 We construct a specific example of a class of traversable wormholes in Einstein-Dirac-Maxwell theory in four spacetime dimensions, without needing any form of exotic matter.
