Classical measure of regularity freg(E)

‹‹‹ B 0.62 1.09   All sections at one B Quantum regularity

Figure 1: freg (B=1.09, E) The same as in Figure 1, but in different scale. Calculated using the sections of regularity (see Figure 2).   The same as in Figure 1, but in different scale. Figure 2: Section of regularity   Poincaré section y=0 calculated on a 100 x 100 grid. A trajectory is started at each point of the grid and the SALI method is used to distinguish regular (blue colour) from chaotic (red colour) trajectories.
