Harmonic Map Analysis of SU(N) Gravitating Skyrmions
Y. Brihaye, B. Hartmann, T. Ioannidou +1
In this paper the SU(N) Einstein-Skyrme system is considered. We express the chiral field (which is not a simple embedding of the SU(2) one) in terms of harmonic maps. In this way,…
On PT-symmetric extensions of the Calogero and Sutherland models
Y. Brihaye, Ancilla Nininahazwe
The original Calogero and Sutherland models describe N quantum particles on the line interacting pairwise through an inverse square and an inverse sinus-square potential. They are…
Born-Infeld strings in brane worlds
Yves Brihaye, Betti Hartmann
We study Born-Infeld strings in a six dimensional brane world scenario recently suggested by Giovannini, Meyer and Shaposhnikov (GMS). In the limit of the Einstein-Abelian-Higgs mo…
Fullerenic solitons
Yves Brihaye, Betti Hartmann
We study a modified non-linear Schroedinger equation on a 2 dimensional sphere with radius R aiming to describe electron-phonon interactions on fullerenes and fullerides. These ele…
Spinning Solitons of a Modified Non-Linear Schroedinger equation
Yves Brihaye, Betti Hartmann, Wojtek J. Zakrzewski
We study soliton solutions of a modified non-linear Schroedinger (MNLS) equation. Using an Ansatz for the time and azimuthal angle dependence previously considered in the studies o…
Quasi exactly solvable (QES) equations with multiple algebraisations
Yves Brihaye, Betti Hartmann
We review three examples of quasi exactly solvable (QES) Hamitonians which possess multiple algebraisations. This includes the most prominent example, the Lame equation, as well as…
