Rigorous properties and uncertainty-like relationships on product-complexity measures: Application to atomic systems

López-Rosa, S.; Angulo, J.C.; Antolín, J. - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 10, pp. 2081-2091

Most of research on complexities and the corresponding conclusions have been obtained by numerically quantifying their values, and little attention has been paid to their theoretical properties and the exact meaning within an statistical framework, valid for any arbitrary n-dimensional...

Entropy in quantum ratchet for a delta-kicked model

Chen, Lei; Li, Chuan-Feng; Gong, Ming; Guo, Guang-Can - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 20, pp. 4328-4332

We investigate the evolution of Shannon entropy in quantum ratchet effect for a delta-kicked model, where a particle … with initial momentum zero is periodically kicked by an asymmetric potential. It is shown that the evolution of Shannon … entropy of the particle can remarkably reflect whether quantum resonance emerges and gives rise to ratchet current or not …

On classes of non-Gaussian asymptotic minimizers in entropic uncertainty principles

Zozor, S.; Vignat, C. - In: Physica A: Statistical Mechanics and its Applications 375 (2007) 2, pp. 499-517

In this paper we revisit the Bialynicki-Birula and Mycielski uncertainty principle and its cases of equality. This Shannon entropic version of the well-known Heisenberg uncertainty principle can be used when dealing with variables that admit no variance. In this paper, we extend this uncertainty...

On Lempel–Ziv complexity for multidimensional data analysis

Zozor, S.; Ravier, P.; Buttelli, O. - In: Physica A: Statistical Mechanics and its Applications 345 (2005) 1, pp. 285-302

In this paper, a natural extension of the Lempel–Ziv complexity for several finite-time sequences, defined on finite size alphabets is proposed. Some results on the defined joint Lempel–Ziv complexity are given, as well as properties in connection with the Lempel–Ziv complexity of the...
