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 ...

Superstatistics in the context of relativity
Physical Review ResearchThe statistical properties of space and astrophysical environments often exhibit heavy-tailed distributions, reflecting deviations from thermal equilibrium.

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.

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.

Novel anomalous diffusion phenomena of underdamped Langevin equation with random parameters
New Journal of Physics, 2021 The diffusion behavior of particles moving in complex heterogeneous environment is a very topical issue. We characterize particle’s trajectory via an underdamped Langevin system driven by a Gaussian white noise with a time dependent diffusivity of ...
