Universe, 2021 Wormholes are hypothetical topologically-non-trivial structures of spacetime. From the theoretical point of view, the possibility of their existence is challenging but cannot be ruled out.

Replica wormholes and the entropy of Hawking radiation [PDF]
Journal of High Energy Physics, 2020 The information paradox can be realized in anti-de Sitter spacetime joined to a Minkowski region. In this setting, we show that the large discrepancy between the von Neumann entropy as calculated by Hawking and the requirements of unitarity is fixed by ...

Yukawa–Casimir Wormholes in f(Q) Gravity [PDF]
Universe, 2023 Casimir energy is always suggested as a possible source to create a traversable wormhole. It is also used to demonstrate the existence of negative energy, which can be created in a lab. To generalize this idea, Yukawa modification of a Casimir source has

Wormholes in the f(R,L,T) theory of gravity [PDF]
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsMorris and Thorne developed wormhole solutions in the late 1980s when they discovered a recipe that wormholes must follow for travelers to cross them safely.

Wormholes without averaging [PDF]
Journal of High Energy Physics, 2021 After averaging over fermion couplings, SYK has a collective field description that sometimes has “wormhole” solutions. We study the fate of these wormholes when the couplings are fixed. Working mainly in a simple model, we find that the wormhole saddles

Quantum corrected charged thin-shell wormholes surrounded by quintessence
European Physical Journal C: Particles and Fields, 2023 In this manuscript, we inspect the stable geometry of thin-shell wormholes in the framework of static, spherically-symmetric quantum corrected charged black hole solution bounded by quintessence.

Stable Lorentzian wormholes in dilatonic Einstein-Gauss-Bonnet theory
Physical Review D, 2012 We discuss the properties of Lorentzian wormholes in dilatonic Einstein-Gauss-Bonnet theory in four spacetime dimensions. These wormholes do not need any form of exotic matter for their existence.

Transparentizing black holes to eternal traversable wormholes
Journal of High Energy Physics, 2019 We present the gravity description of evaporating black holes that end up with eternal traversable wormholes where every would-be behind horizon degree is available in asymptotic regions.

Replica wormholes and the black hole interior [PDF]
Journal of High Energy Physics, 2022 Recent work has shown how to obtain the Page curve of an evaporating black hole from holographic computations of entanglement entropy. We show how these computations can be justified using the replica trick, from geometries with a spacetime wormhole ...

Nuclear Physics BIn this study, we investigate traversable wormholes inspired by the Kiselev framework, which extends classical black hole solutions by incorporating anisotropic fluids.
