Quasi-Power Law Ensembles: Nonextensive Statistics or Superstatistics [PDF]
EntropyIn phenomenological studies of multiparticle production, transverse-momentum spectra measured in experiments frequently display an approximately power-law falloff, for which the Tsallis-type functional form is commonly employed as an effective ...

Recent developments in superstatistics [PDF]
Brazilian Journal of Physics, 2009 We provide an overview on superstatistical techniques applied to complex systems with time scale separation. Three examples of recent applications are dealt with in somewhat more detail: the statistics of small-scale velocity differences in Lagrangian ...

Superstatistical generalised Langevin equation: non-Gaussian viscoelastic anomalous diffusion [PDF]
New Journal of Physics, 2018 Recent advances in single particle tracking and supercomputing techniques demonstrate the emergence of normal or anomalous, viscoelastic diffusion in conjunction with non-Gaussian distributions in soft, biological, and active matter systems.

Superstatistics in nanoscale electrochemical systems. [PDF]
Proc Natl Acad Sci U S A, 2011 Stochastic electrochemical reaction steps on nanosized electrodes are non-Markovian when externally driven by an applied voltage. We show that, compared to the Markovian case (when external driving is absent), nanoscale electrochemical systems obey a superstatistics characterized by a superposition of Tsallis’ q ...

Wind Power Persistence Characterized by Superstatistics. [PDF]
Sci Rep, 2019 AbstractMitigating climate change demands a transition towards renewable electricity generation, with wind power being a particularly promising technology. Long periods either of high or of low wind therefore essentially define the necessary amount of storage to balance the power system. While the general statistics of wind velocities have been studied

Fundraising and vote distribution: A non-equilibrium statistical approach. [PDF]
PLoS ONE, 2019 The number of votes correlates strongly with the money spent in a campaign, but the relation between the two is not straightforward. Among other factors, the output of a ballot depends on the number of candidates, voters, and available resources.

Microscopic Fluctuations in Power‐Grid Frequency Recordings at the Subsecond Scale
Complexity, Volume 2023, Issue 1, 2023., 2023 Complex systems, such as the power grid, are essential for our daily lives. Many complex systems display multifractal behavior, correlated fluctuations and power laws. Whether the power‐grid frequency, an indicator of the balance of supply and demand in the electricity grid, also displays such complexity remains a mostly open question.

Superstatistical two-temperature Ising model [PDF]
Physical Review E, 2021 The previous approach of the nonequilibrium Ising model was based on the local temperature in which each site or part of the system has its own specific temperature. We introduce an approach of the two-temperature Ising model as a prototype of the superstatistic critical phenomena.

Universality of market superstatistics [PDF]
Physical Review E, 2016 We use a continuous-time random walk (CTRW) to model market fluctuation data from times when traders experience excessive losses or excessive profits. We analytically derive "superstatistics" that accurately model empirical market activity data (supplied by Bogachev, Ludescher, Tsallis, and Bunde)that exhibit transition thresholds.

Log-Normal Superstatistics for Brownian Particles in a Heterogeneous Environment
Physics, 2020 Superstatistical approaches have played a crucial role in the investigations of mixtures of Gaussian processes. Such approaches look to describe non-Gaussian diffusion emergence in single-particle tracking experiments realized in soft and biological ...
