Ricci inverse gravity wormholes [PDF]
Physics Letters B, 2023 The current study deals with the new wormhole solutions in the background of fourth order new modified Ricci inverse gravity. Two new classes of the wormhole solutions are analyzed by showing the valid region for the main part of wormhole geometry under ...

Transcending the ensemble: baby universes, spacetime wormholes, and the order and disorder of black hole information [PDF]
Journal of High Energy Physics, 2020 In the 1980’s, work by Coleman and by Giddings and Strominger linked the physics of spacetime wormholes to ‘baby universes’ and an ensemble of theories.

Wormholes without exotic matter: quasinormal modes, echoes and shadows [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 An analytical solution representing traversable asymptotically flat and symmetric wormholes was obtained without adding exotic matter in two different theories independently: in the Einstein-Maxwell-Dirac theory and in the second Randall-Sundrum brane ...

Casimir wormholes in modified symmetric teleparallel gravity [PDF]
The European Physical Journal C, 2022 In recent years there has been a growing interest in the field of Casimir wormhole. In classical general relativity (GR), it is known that the null energy condition (NEC) has to be violated to have a wormhole to be stable.

AI & SOCIETY, 2021 AbstractCameras, microphones, and other sensors continue to proliferate in the world around us. I offer a new metaphor for conceptualizing these technologies: they are digital wormholes, transmitting representations of human persons between disparate points in space–time.

Tideless traversable wormholes surrounded by cloud of strings in f(R) gravity [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 We study the tideless traversable wormholes in the f(R) gravity metric formalism. First we consider three shape functions of wormholes and study their viabilities and structures.

The European Physical Journal C, 2023 This article evaluates the stability constraints of higher-dimensional geometry of thin-shell wormholes developed from the two equivalent copies of inner and outer d -dimensional charged anti-de Sitter black holes bounded by a cloud of strings and ...

Classical and quantum gravity, 2021 We explore the construction and stability of asymptotically anti-de Sitter Euclidean wormholes in a variety of models. In simple ad hoc low-energy models, it is not hard to construct two-boundary Euclidean wormholes that dominate over disconnected ...

Bra-ket wormholes in gravitationally prepared states [PDF]
Journal of High Energy Physics, 2020 We consider two dimensional CFT states that are produced by a gravitational path integral. As a first case, we consider a state produced by Euclidean AdS2 evolution followed by flat space evolution.
