Novel anomalous diffusion phenomena of underdamped Langevin equation with random parameters

open access: yesNew 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 ...

Demystifying the success of empirical distributions in space plasmas

open access: yesPhysical Review Research, 2020
Motivated by the recent result by Davis et al. [Phys. Rev. E 100, 023205 (2019)2470-004510.1103/PhysRevE.100.023205] that velocity distributions of collisionless steady-state plasmas must follow superstatistics, we examine systematically the ability of ...

Spatio-temporal complexity of power-grid frequency fluctuations

open access: yesNew Journal of Physics, 2021
Power-grid systems constitute one of the most complex man-made spatially extended structures. These operate with strict operational bounds to ensure synchrony across the grid.

Effects of cosmic-string framework on the thermodynamical properties of anharmonic oscillator using the ordinary statistics and the q-deformed superstatistics approaches

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
In this article, we determine the thermodynamical properties of the anharmonic canonical ensemble within the cosmic-string framework. We use the ordinary statistics and the q-deformed superstatistics for this study.

Superstatistical approach to air pollution statistics

open access: yesPhysical Review Research, 2020
Air pollution by nitrogen oxides (NO_{x}) is a major concern in large cities as it has severe adverse health effects. However, the statistical properties of air pollutants are not fully understood.

Skewed superstatistical distributions from a Langevin and Fokker-Planck approach [PDF]

open access: yes, 2010
The superstatistics concept is a useful statistical method to describe inhomogeneous complex systems for which a system parameter $\beta$ fluctuates on a large spatio-temporal scale.

Superstatistics in Econophysics [PDF]

open access: yes, 2003
We consider an ideal closed stock market, in which 100 traders have economic activities. The assets of the traders change through buying and selling stocks. We simulate the assets under conservation of both total currency and total number of stocks. If the traders are identical, then the assets are distributed as a stationary Gaussian.

First-passage time for superstatistical Fokker-Planck models [PDF]

open access: yes, 2018
The first-passage-time (FPT) problem is studied for superstatistical models assuming that the mesoscopic system dynamics is described by a Fokker-Planck equation.
