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. Restricting to a model with two massive fermions in a singlet spinor state, we show the existence of spherically symmetric asymptotically flat configurations which are free of singularities, representing localized states. These solutions satisfy a generalized Smarr relation, being connected with the extremal Reissner…

Transmission of low-energy scalar waves through a traversable wormhole
We study the scattering of low-energy massless and massive minimally coupled scalar fields by an asymptotically flat traversable wormhole. We provide a comprehensive treatment of this problem
A Note on “Traversable Wormholes in Einstein–Dirac–Maxwell Theory”
Abstract In their Letter [Phys. Rev. Lett. 126 , 101102 (2021); arXiv: 2010.07317], J.L. Blázquez-Salcedo, C. Knoll, and E. Radu have constructed a very interesting class of wormhole solutions in
Blázquez-Salcedo–Knoll–Radu wormholes are not solutions to the Einstein-Dirac-Maxwell equations
Recently, Blázquez-Salcedo, Knoll, and Radu (BSKR) have given a class of static, spherically symmetric, traversable wormhole spacetimes with Dirac and Maxwell fields. The BSKR wormholes are obtained

Appearance of Keplerian discs orbiting on both sides of reflection-symmetric wormholes
We construct optical appearance and profiled spectral lines of Keplerian discs with inner edge at the innermost circular geodesic located on both sides of reflection-symmetric Simpson-Visser
Bardeen-Kiselev black hole with a cosmological constant
In this work we analyze a solution that mimics the Bardeen solution with a cosmological constant surrounded by quintessence. We show that this solution can be obtained by Einstein equations coupled
Echoes from asymmetric wormholes and black bounce
The time evolutions of the field perturbations in certain asymmetric wormhole and black bounce backgrounds are investigated. It is found that the echo signals arise only in some wormhole cases. We

In this short review, we present some recently obtained traversable wormhole models in the framework of general relativity (GR) in four and six dimensions that somehow widen our common ideas on
Epicyclic Oscillations around Simpson–Visser Regular Black Holes and Wormholes
We study epicyclic oscillatory motion along circular geodesics of the Simpson–Visser metageometry describing in a unique way regular black-bounce black holes and reflection-symmetric wormholes by
