Describing and, to a certain extent, understanding the concept of complexity has been
investigated in a variety of research fields. Various ad hoc formal definitions and …

▪ Abstract Coherent control of atomic and molecular processes has been a rapidly
developing field. Applications of coherent control to large and complex molecular systems …

Entanglement production in coupled chaotic systems is studied with the help of kicked tops.
Deriving the correct classical map, we have used the reduced Husimi function, the Husimi …

We give a new explanation for why some biological systems can stay quantum coherent for
a long time at room temperature, one of the fundamental puzzles of quantum biology. We …

Using the symplectic tomography map, both for the probability distributions in classical
phase-space and for the Wigner functions of its quantum counterpart, we discuss a notion of …

We study the statistical and dynamical properties of the quantum triangle map, whose
classical counterpart can exhibit ergodic and mixing dynamics, but is never chaotic …

We discuss the connection between the out-of-time-ordered correlator and the number of
harmonics of the phase-space Wigner distribution function. In particular, we show that both …

We establish that the entropy production rate of a classically chaotic Hamiltonian system
coupled to the environment settles, after a transient, to a metastable value given by the sum …

We discuss the roles of the macroscopic limit and different system-environment interactions
in a quantum-classical transition for a chaotic system. We consider the kicked harmonic …

In classical mechanics the complexity of a dynamical system is characterized by the rate of
local exponential instability which effaces the memory of initial conditions and leads to …
