Hamiltonian integrable systems in a magnetic field and Symplectic-Haantjes geometry (2401.16897v2)
Published 30 Jan 2024 in math-ph, math.DG, math.MP, and nlin.SI
Abstract: We investigate the geometry of classical Hamiltonian systems immersed in a magnetic field in three-dimensional Riemannian configuration spaces. We prove that these systems admit non-trivial symplectic-Haantjes manifolds, which are symplectic manifolds endowed with an algebra of Haantjes (1,1)-tensors. These geometric structures allow us to determine separation variables for known systems algorithmically; besides, the underlying St\"ackel geometry is used to construct new families of integrable Hamiltonian models immersed in a magnetic field.
