Abstract: | A finite Heisenberg magnetic ring with an arbitrary single-node spin and two spin deviations from the ferromagnetic saturation
is considered as the system of two Bethe pseudoparticles. The set of all relevant magnetic configurations spans a surface
which can be recognised as a Mőbius strip. The dynamics of the system imposes the double twist of all regular orbits of the
translation symmetry group. |
