## 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 *PT*-symmetric dynamical models in complex phase space exhibit strong qualitative similarities.

*J. Phys. A: Math. Theor.***40**, F397 (2007) ref. [27]. The motivation in these papers was to study the effects of classical chaos on semiclassical tunnelling. In the instanton calculus one must deal with a complex configuration space. Additional complex studies are found in refs [28–30]Google Scholar - [27]A Ishikawa, A Tanaka and A Shudo,

*K*and*g*become imaginary the system becomes invariant under combined*PT*reflection. However, now*P*is the spatial reflection,*P*:*θ → θ*+*π*, so that both cos*θ*and sin*θ*, and thus the Cartesian coordinates, change sign. The sign of the angular momentum now remains unchanged under parity reflection. This explains the symmetry of the plots when*K*and*g*are pure imaginary (see figure 9 and the lower-right plot in figure 11 respectively). This change of symmetry of the system as its couplings vary in complex parameter space is not unusual. For example, at a generic point in coupling space for the three-dimensional anisotropic harmonic oscillator, the only symmetry is parity. However, when any two couplings coincide and are different from the third, the reflection symmetry is enhanced and becomes a continuous symmetry, namely, an*O*(2) symmetry around the third axis. (There remains parity-time reflection symmetry in the third direction.) When all three couplings coincide, the symmetry is enhanced further and becomes a full*O*(3) symmetryGoogle Scholar - [34]C M Bender and S A Orszag,
