Wormholes in Einstein-Dirac-Maxwell theory with identical spacetime asymptotics
arXiv:2510.03656 · doi:10.1140/epjc/s10052-026-15456-y
Abstract
Within general relativity, we study spherically symmetric configurations with wormhole topology consisting of spinor fields and a Maxwell electric field. For such a system, we construct complete families of regular asymmetric solutions describing wormholes connecting two identical Minkowski spacetimes. The physical properties of such systems are completely determined by the values of three input quantities: the throat parameter, the spinor frequency, and the coupling constant. Depending on the specific values of these parameters, the configurations may have essentially different characteristics, including negative ADM masses.
