Query: Non Perturbative Destruction of Localization in the Quantum Kicked
  Particle Problem   The angle coordinate of the Quantum Kicked Rotator problem is treated as if
it were an extended coordinate. A new mechanism for destruction of coherence by
noise is analyzed using both heuristic and formal approach. Its effectiveness
constitutes a manifestation of long-range non-trivial dynamical correlations.
Perturbation theory fails to quantify certain aspects of this effect. In the
perturbative case, for sufficiently weak noise, the diffusion coefficient
${\cal D}$ is just proportional to the noise intensity $\nu$. It is predicted
that in some generic cases one may have a non-perturbative dependence ${\cal
D}\propto\nu^{\alpha}$ with $0.35 < \alpha < 0.38$ for arbitrarily weak noise.
This work has been found relevant to the recently studied ionization of H-atoms
by a microwave electric field in the presence of noise. Note added (a):
Borgonovi and Shepelyansky have adopted this idea of non-perturbative
transport, and have demonstrated that the same effect manifests itself in the
tight-binding Anderson model with the same exponent $\alpha$. Note added (b):
The recent interest in the work reported here comes from the experimental work
by the Austin group and by the Auckland group. In these experiment the QKP
model is realized literally. However, the novel effect of non-perturbative
transport, reported in this Letter, has not been tested yet.
