Wormholes Immersed in Rotating Matter

Christian Hoffmann, Theodora Ioannidou, Sarah Kahlen +2

We consider Ellis wormholes immersed in rotating matter in the form of an ordinary complex boson field. The resulting wormholes may possess full reflection symmetry with respect to…

Symmetric and Asymmetric Wormholes Immersed In Rotating Matter

Christian Hoffmann, Theodora Ioannidou, Sarah Kahlen +2

We consider four-dimensional wormholes immersed in bosonic matter. While their existence is based on the presence of a phantom field, many of their interesting physical properties…

Wormholes Immersed in Rotating Matter

Christian Hoffmann, Theodora Ioannidou, Sarah Kahlen +2

We demonstrate that rotating matter sets the throat of an Ellis wormhole into rotation, allowing for wormholes which possess full reflection symmetry with respect to the two asympt…

Spontaneous Symmetry Breaking in Wormholes Spacetimes with Matter

Christian Hoffmann, Theodora Ioannidou, Sarah Kahlen +2

When bosonic matter in the form of a complex scalar field is added to Ellis wormholes, the phenomenon of spontaneous symmetry breaking is observed. Symmetric solutions possess full…

Wormholes Threaded by Chiral Fields

Efstathios Charalampidis, Theodora Ioannidou, Burkhard Kleihaus +1

We consider Lorentzian wormholes with a phantom field and chiral matter fields. The chiral fields are described by the non-linear sigma model with or without a Skyrme term. When th…

Spinning Gravitating Skyrmions

Theodora Ioannidou, Burkhard Kleihaus, Jutta Kunz

We investigate self-gravitating rotating solutions in the Einstein-Skyrme theory. These solutions are globally regular and asymptotically flat. We present a new kind of solutions w…
