"A Solvable Hamiltonian System" Integrability and Action-Angle Variables
Abstract
We prove that the dynamical system charaterized by the Hamiltonian $ H = λN \sum_{j}^{N} p_j + μ\sum_{j,k}^{N} {{(p_j p_k)}^{1\over 2}} \{ cos [ ν( q_j - q_k)] \} $ proposed and studied by Calogero [1,2] is equivalent to a system of {\it non-interacting} harmonic oscillators. We find the explicit form of the conserved currents which are in involution. We also find the action-angle variables and solve the initial value problem in simple form.
