Rotating wormholes in five dimensions with equal angular momenta: large asymmetry regime
Keiya Uemichi, Yasutaka Koga, Daiki Saito +2
We clarify the relationship between rotation and the energy condition for stationary rotating wormhole solutions of the Einstein equations coupled to a phantom field in five-dimens…

Dynamical Formation of Charged Wormholes
Yasutaka Koga, Ryota Maeda, Daiki Saito +2
We construct static, spherically symmetric, charged traversable wormhole solutions to the Einstein--Maxwell equations, supported by bidirectional (ingoing and outgoing) null dust w…

Multi-Sheet Wormholes in the Gravitational Soliton Formalism
Yusuke Makita, Keisuke Izumi, Daisuke Yoshida +1
We analytically construct static regular solutions describing wormholes that connect multiple asymptotic regions, supported by a phantom scalar field. The solutions are static and…
