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…
Extreme events in near integrable lattices
C. Hoffmann, E. G. Charalampidis, D. J. Frantzeskakis +1
In the present work, we examine the potential robustness of extreme wave events associated with large amplitude fluctuations of the Peregrine soliton type, upon departure from the…
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…
Boson Stars with Nontrivial Topology
Vladimir Dzhunushaliev, Vladimir Folomeev, Christian Hoffmann +2
We construct boson star solutions in the presence of a phantom field, allowing for a nontrivial topology of the solutions. The wormholes residing at the core of the configurations…
