Random walk is a fundamental concept with applications ranging from quantum physics to
econometrics. Remarkably, one specific model of random walks appears to be ubiquitous …

Statistical mechanics constitutes one of the pillars of contemporary physics. Recognized as
such-together with mechanics (classical, quantum, relativistic), electromagnetism and …

Metaphors, generalizations and unifications are natural and desirable ingredients of the
evolution of scientific theories and concepts. Physics, in particular, obviously walks along …

As early as 1902, Gibbs pointed out that systems whose partition function diverges, eg
gravitation, lie outside the validity of the Boltzmann–Gibbs (BG) theory. Consistently, since …

Controlling the motional degrees of isolated, single nanoparticles trapped within optical
fields in a high vacuum are seen as ideal candidates for exploring the limits of quantum …

The formalism of statistical mechanics can be generalised by starting from more general
measures of information than the Shannon entropy and maximising those subject to suitable …

Definition The concept of entropy constitutes, together with energy, a cornerstone of
contemporary physics and related areas. It was originally introduced by Clausius in 1865 …

This paper describes the physical foundations of the newly discovered “entropy defect” as a
basic concept of thermodynamics. The entropy defect quantifies the change in entropy …

We present an investigation for the generation of a dust-acoustic rogue wave in a dusty
plasma composed of negatively charged dust grains, as well as nonextensive electrons and …

We experimentally study anomalous diffusion of ultracold atoms in a one dimensional
polarization optical lattice. The atomic spatial distribution is recorded at different times and …
