Hedgehog ansatz and its generalization for self-gravitating Skyrmions
- Physics
- 2013
The hedgehog ansatz for spherically symmetric spacetimes in self-gravitating nonlinear sigma models and Skyrme models is revisited and its generalization for nonspherically symmetric spacetimes is…
Analytic non-Abelian gravitating solitons in the Einstein–Yang–Mills–Higgs theory and transitions between them
- PhysicsThe European Physical Journal C
- 2021
Two analytic examples of globally regular non-Abelian gravitating solitons in the Einstein–Yang–Mills–Higgs theory in (3 + 1)-dimensions are presented. In both cases, the space-time geometries are of…
Experimental and Theoretical Evidence for Extended Particle Models
- Physics
- 2010
We review the experimental searches on those interactions where the fundamental particles could exhibit a non point-like behavior. In particular we focus on the QED reaction measuring the…

Regular and Black Hole Skyrmions with Axisymmetry
- Physics
- 2004
It has been known that a B=2 skyrmion is axially symmetric. We consider the Skyrme model coupled to gravity and obtain static axially symmetric regular and black hole solutions numerically. Computing…

Harmonic map analysis of SU ( N ) gravitating Skyrmions
- Physics
- 2004
In this paper the $\mathrm{SU}(N)$ Einstein-Skyrme system is considered. We express the chiral field [which is not a simple embedding of the $\mathrm{SU}(2)$ field] in terms of harmonic maps. In this…
SU(N) skyrmions and harmonic maps
- Physics, Mathematics
- 1999
Harmonic maps from S2 to CPN−1 are introduced to construct low-energy configurations of the SU(N) Skyrme model. We show that one of such maps gives an exact, topologically trivial, solution of the…
