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… Expand

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 problemExpand
A note on"Traversable wormholes in Einstein-Dirac-Maxwell theory"
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 generalExpand
The Bl\'azquez-Salcedo, Knoll, and 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 obtainedExpand
Appearance of Keplerian discs orbiting on both sides of a reflection-symmetric wormhole
Abstract We construct optical appearance and profiled spectral lines of Keplerian discs with inner edge at the innermost circular geodesic located on both sides of the reflection-symmetricExpand
Echoes from Asymmetric Wormholes and Black Bounce
The time evolution of the field perturbations in the wormhole and black bounce backgrounds are investigated. We find that the asymmetry of spacetime results in the asymmetry of the effectiveExpand

Epicyclic orbits in the field of Einstein–Dirac–Maxwell traversable wormholes applied to the quasiperiodic oscillations observed in microquasars and active galactic nuclei

Free energy landscape and kinetics of phase transition in two coupled SYK models
We propose that the thermodynamics and the kinetics of the phase transition between wormhole and two black hole described by the two coupled SYK model can be investigated in terms of the stochasticExpand
General parametrization of wormhole spacetimes and its application to shadows and quasinormal modes
The general parametrization for spacetimes of spherically symmetric Lorentzian, traversable wormholes in an arbitrary metric theory of gravity is presented. The parametrization is similar in spiritExpand
