Semilinear Response
@inproceedings{Wilkinson2005SemilinearR, title={Semilinear Response}, author={Michael Wilkinson and Bernhard Mehlig and Doron Cohen}, year={2005} }
. – We discuss the response of a quantum system to a time-dependent perturbation with spectrum Φ( ω ). This is characterised by a rate constant D describing the diffusion of occupation probability between levels. We calculate the transition rates by first order perturbation theory, so that multiplying Φ( ω ) by a constant λ changes the diffusion constant to λD . However, we discuss circumstances where this linearity does not extend to the function space of intensities, so that if intensities Φ i…

We make a distinction between the spectroscopic and the mesoscopic conductance of a closed ring. We show that the latter is not simply related to the Landauer conductance of the corresponding open…

The analysis of diffusive energy spreading in quantized chaotic driven systems leads to a universal paradigm for the emergence of a quantum anomaly. In the classical approximation, a driven chaotic…

Abstract
We study motion of a quantum wavepacket in a one-dimensional potential with correlated
disorder. Presence of long-range potential correlations allows for existence of both
localized and…
The mesoscopic conductance of disordered rings, its random matrix theory and the generalized variable range hopping picture
- Biology

It is argued that the texture and the sparsity of the perturbation matrix dictate the value of the conductance, and its dependence on the disorder strength, ranging from the ballistic to the Anderson localization regime is studied.
