Science is not merely the smooth progressive interaction of hypothesis, experiment and
theory, although it sometimes has that form. More realistically the scientific study of any …

Cold atoms in dissipative optical lattices exhibit an unusual transport behaviour that cannot
be described within Boltzmann–Gibbs statistical mechanics. New theoretical tools and …

Scientists have grappled with reconciling biological evolution 1, 2 with the immutable laws of
the Universe defined by physics. These laws underpin life's origin, evolution and the …

We investigate fractional Brownian motion with a microscopic random-matrix model and
introduce a fractional Langevin equation. We use the latter to study both subdiffusion and …

We demonstrated experimentally that the momentum distribution of cold atoms in dissipative
optical lattices is a Tsallis distribution. The parameters of the distribution can be continuously …

The continuous-time random walk (CTRW) model exhibits a nonergodic phase when the
average waiting time diverges. Using an analytical approach for the nonbiased and the …

We discuss a renewal process in which successive events are separated by scale-free
waiting time periods. Among other ubiquitous long-time properties, this process exhibits …

→∞, extremely long jumps may occur, and typical trajectories are self-similar, on all scales
showing clusters of shorter jumps intersparsed by long excursions. In fact, the trajectory of a …

Classical collisions with an ideal gas generate non-Maxwellian distribution functions for a
single ion in a radio frequency ion trap. The distributions have power-law tails whose …

The minimum-bias multiplicity distribution and the transverse momentum and pseudorapidity
distributions for central collisions have been measured for negative hadrons (h−) in Au+ Au …
