# Semilinear Response

. – 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…

We study motion of a quantum wavepacket in a one-dimensional potential with correlated

- 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.
