    • Abstract


      This paper examines numerically the complex classical trajectories of the kicked rotor and the double pendulum. Both of these systems exhibit a transition to chaos, and this feature is studied in complex phase space. Additionally, it is shown that the short-time and long-time behaviours of these two $\mathcal{PT}$ -symmetric dynamical models in complex phase space exhibit strong qualitative similarities.
