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.
