Abstract

A dynamical phase transition from integrability to non-integrability for a family of 2-D Hamiltonian mappings whose angle, theta, diverges in the limit of vanishingly action, I, is characterised. The mappings are described by two parameters: (i) epsilon, controlling the transition from integrable (epsilon = 0) to non-integrable (epsilon not equal 0); and (ii) gamma, denoting the power of the action in the equation which defines the angle. We prove the average action is scaling invariant with respect to either epsilon or n and obtain a scaling law for the three critical exponents. (C) 2015 Elsevier B.V. All rights reserved.
