Quantized chaotic systems are generically characterized by two energy
scales: the mean level spacing and the bandwidth.
This implies that with respect to driving such systems have an adiabatic,
a perturbative and a non-perturbative regimes. A \"strong\" quantal
non-perturbative response effect is found for systems that are described
by random matrix theory models.
Is there a similar effect for quantized \"chaotic\" systems ?
Theoretical arguments cannot exclude the existence of a \"weak\"
non-perturbative response effect, but detailed numerical investigations
results in an unexpected degree of semiclassical correspondence.
