Collective superintegrable systems from the Guillemin--Sternberg torus action
L. Feher
We present a novel approach to the superintegrability of collective Hamiltonians invariant under a Hamiltonian action of a connected semisimple compact Lie group, , on a symplec…
Spherical singularities in compactified Ruijsenaars--Schneider systems
L. Feher, H. R. Dullin
We investigate certain Liouville integrable systems constructed earlier via reduction of the quasi-Hamiltonian double of . These systems live on compact connected s…
Integrable systems from Poisson reductions of generalized Hamiltonian torus actions
L. Feher, M. Fairon
We develop a set of sufficient conditions for guaranteeing that an integrable system with a symmetry group on a manifold descends to an integrable system on a dense open su…
Hidden symmetries of a self-dual monopole
L. Feher, P. Horvathy, L. O'Raifeartaigh
The symmetries of a spinning particle in the field of a self-dual monopole are studied from the viewpoint of supersymmetric quantum mechanics.
Applications of chiral supersymmetry for spin fields in self-dual backgrounds
L. Fehér, P. A. Horváthy, L. O'Raifeartaigh
Due to chiral supersymmetry the (nonzero mode) spectral and symmetry properties of a 4-dimensional, self-dual Dirac-Yang-Mills operator $\D$ can be recovered from those of the corr…
