Time-reversibility measured by the deviation of perturbed time-reversed motion from the unperturbed motion is examined for normal quantum diffusion exhibited by four classes of quantum maps with contrasting physical nature. Irrespective of the system, there exists a universal minimal quantum threshold above which the system completely loses memory of the past. The time-reversed dynamics as well as the time-reversal characteristics are asymptotically universal curves independent of the details…

Time-reversal characteristics of quantum normal diffusion
Abstract This paper concerns the time-reversal characteristics of intrinsic normal diffusion in quantum systems. Time-reversible properties are quantified by the time-reversal test; the system
Time-reversal characteristics of quantum normal diffusion: time-continuous models
In quantum map systems exhibiting normal diffusion, time-reversal characteristics converge to a universal scaling behavior which implies a prototype of irreversible quantum process [H.S. Yamada, K.S.

Time reversibility of quantum diffusion in small-world networks
We study the time-reversal dynamics of a tight-binding electron in the Watts-Strogatz (WS) small-world networks. The localized initial wave packet at time t = 0 diffuses as time proceeds until the
Critical phenomena of dynamical delocalization in quantum maps: Standard map and Anderson map.
The self-consistent theory (SCT) of the localization is applied, taking a plausible hypothesis on the mean-free-path parameter which worked successfully in the analyses of the monochromatically perturbed QMs and comparing in detail the numerical results with the predictions of the SCT.
Scaling properties of dynamical localization in monochromatically perturbed quantum maps: Standard map and Anderson map.
Dynamical localization phenomena of monochromatically perturbed standard map (SM) and Anderson map (AM), which are both identified with a two-dimensional disordered system under suitable conditions,
Localization and delocalization properties in quasi-periodically perturbed Kicked Harper and Harper models
We numerically study the single particle localization and delocalization phenomena of an initially localized wave packet in the kicked Harper model (KHM) and Harper model subjected to quasiperiodic
Analyticity of quantum states in one-dimensional tight-binding model
Analytical complexity of quantum wavefunction whose argument is extended into the complex plane provides an important information about the potentiality of manifesting complex quantum dynamics such
