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 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-symmetric
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 effective
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
Epicyclic orbits in the field of Einstein–Dirac–Maxwell traversable wormholes applied to the quasiperiodic oscillations observed in microquasars and active galactic nuclei
We study the epicyclic oscillatory motion around circular orbits of the traversable asymptotically flat and reflection-symmetric wormholes obtained in the Einstein-Dirac-Maxwell theory without
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 stochastic
