We show numerically that a finite isolated cluster of interacting spins 1/2 exhibits a surprising
nonthermal statistics when subjected to a series of small nonadiabatic perturbations by an …

We consider the notion of equilibration for an isolated quantum system exhibiting Anderson
localization. The system is assumed to be in a pure state, ie, described by a wave-function …

The response of a quantum system in a pure state to an external force is investigated by
reconsidering the standard statistical approach to quantum dynamics in the light of the …

Despite the quantum nature of molecules, classical mechanics is often employed to describe
molecular motions that play a fundamental role in a wide range of phenomena including …

Descriptions of molecular systems usually refer to two distinct theoretical frameworks. On the
one hand the quantum pure state, ie, the wavefunction, of an isolated system is determined …

The decoherence of a central electron spin of an atom coupled to an anti-ferromagnetic spin
bath in the presence of a time varying B-Field (VBF) is investigated applying the Holstein …

The representation of a quantum system as the spatial configuration of its constituents
evolving in time as a trajectory under the action of the wave-function, is the main objective of …

The usual approach to the foundations of quantum statistical physics is based on the
conventional micro-canonical ensemble as a starting point for deriving the Boltzmann–Gibbs …

We introduce a stability criterion for quantum statistical ensembles describing macroscopic
systems. An ensemble is called “stable” when a small number of local measurements cannot …

Molecular systems are quantum systems, but the complete characterization of molecular
motions within a fully quantum framework might appear to be an unfeasible task because it …
