The SU(2) Lie-Poisson Algebra and its Descendants

Jin Dai, Theodora Ioannidou, Antti Niemi

In this paper, a novel discrete algebra is presented which follows by combining the SU(2) Lie-Poisson bracket with the discrete Frenet equation. Physically, the construction descri…

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…

Discrete BPS Skyrmions

M. Agaoglou, E. G. Charalampidis, T. A. Ioannidou +1

A discrete analogue of the extended Bogomolny-Prasad-Sommerfeld (BPS) Skyrme model that admits time-dependent solutions is presented. Using the spacing h of adjacent lattice nodes…

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…
