Pk. Papachristou et al., Nonperiodic delay mechanism and fractallike behavior in classical time-dependent scattering - art. no. 016205, PHYS REV E, 6401(1), 2001, pp. 6205
We study the occurrence of delay mechanisms other than periodic orbits in s
cattering systems with time-dependent potentials. By using as model system
two harmonically oscillating disks on a plane, we have found the existence
of a mechanism not related to the periodic orbits of the system, that delay
s trajectories in the scattering region. This mechanism creates a fractalli
ke structure in the scattering functions and can possibly occur in several
time-dependent scattering systems.
