Non-crystallographic reduction of generalized Calogero–Moser models

Abstract: We apply a recently introduced reduction procedure based on the embedding of non-crystallographic Coxeter groups into crystallographic ones to Calogero-Moser systems. For rational potentials the familiar generalized Calogero Hamiltonian is recovered. For the Hamiltonians of trigonometric, hyperbolic and elliptic type, we obtain novel integrable dynamical systems with a second potential term which is rescaled by the golden ratio. We explicitly show for the simplest of these non-crystallographic models how the c… Show more

“…For example, the organisation of different fullerene shells of carbon onions has been modelled with previous approaches ( [19], [42]), and we expect that our new approach should be relevant in this context as well. Moreover, a mathematical formulation of systems with non-crystallographic symmetries is a challenge in wider areas of physics, such as integrable systems, where models in terms of non-crystallographic root systems have been introduced ([43], [44]); we expect that the use of projections of the higher dimensional symmetry groups, that contain non-crystallographic symmetries as crystallographic embeddings, could provide a new perspective also in this context.…”

“…Finally let us note a few more open questions. Do there exist Sutherland models for the exceptional complex reflection groups, perhaps via reduction as in [36]? The Sutherland model is the trigonometric member of the Calogero-Moser family: can one generalize to elliptic potentials?…”

“…Our detailed analysis of the embedding of non-crystallographic into crystallographic Coxeter groups allows one to apply the aforementioned reduction method to a wide range of application in physics, chemistry and biology, where Coxeter groups play a role. For instance in our forthcoming publication [51] we will apply this method to the generalized Calogero-Moser models.…”
