Contribution

It introduces a new class of rotating wormhole solutions with specific physical properties determined by three input parameters, connecting two Minkowski spacetimes.

Findings

Solutions are asymmetric, regular, and asymptotically flat.

Wormholes carry nonzero total angular momentum.

Configurations are fully determined by throat parameter, spinor frequency, and electromagnetic coupling.

Abstract

We consider rotating wormhole solutions in general relativity supported by a complex non-phantom spinor field (which provides a nontrivial spacetime topology) and electromagnetic fields. The solutions are asymmetric, regular, asymptotically flat and carry nonzero total angular momentum. The physical properties of the resulting configurations are completely determined by the values of three input quantities: the throat parameter, the spinor frequency, and the electromagnetic coupling constant. The wormholes connect two identical Minkowski spacetimes possessing in general different masses and global charges.
