We perform Brownian dynamics simulations for studying the self-diffusion in two-dimensional (2D) dusty-plasma liquids, in terms of both mean-square displacement and the velocity autocorrelation function (VAF). Superdiffusion of charged dust particles has been observed to be the most significant at an infinitely small damping rate gamma for intermediate coupling strength, where the long-time asymptotic behavior of VAF is found to be the product of t;{-1} and exp(-gammat). The former represents… Expand

Self-diffusion in a stochastically heated two-dimensional dusty plasma
Diffusion in a two-dimensional dusty plasma liquid (i.e., a Yukawa liquid) is studied experimentally. The dusty plasma liquid is heated stochastically by a surrounding three-dimensional toroidalExpand
Active turbulence in a dusty plasma monolayer
This work presents a theoretical investigation of active turbulence in a dusty plasma monolayer, where energy is injected at the individual particle level and transported to larger scales, leading toExpand
Wave spectra of two-dimensional dusty plasma solids and liquids.
Brownian dynamics simulations were carried out to study wave spectra of two-dimensional dusty plasma liquids and solids for a wide range of wavelengths. The existence of a longitudinal dust-thermalExpand
Self-diffusion in two-dimensional quasimagnetized rotating dusty plasmas.
TLDR
The experimental results confirm the predictions of the simulations: superdiffusive behavior is found at intermediate timescales and the dependence of the self-diffusion coefficient on the magnetic field is well reproduced. Expand
Experimental measurement of non-Markovian dynamics and self-diffusion in a strongly coupled plasma

Is diffusion anomalous in two-dimensional Yukawa liquids?
TLDR
Here it is shown that the results crucially depend on the strength of dissipation and the time instant of the measurement, and that, in the long-time limit, anomalous diffusion vanishes and the system returns to normal diffusion. Expand

Fickian yet non-Gaussian diffusion in two-dimensional Yukawa liquids.
TLDR
Surprisingly, it is found that Fickian diffusion in two-dimensional Yukawa liquids deviate from Gaussian at intermediate timescales, indicating the failure of the Gaussian approximation. Expand

TLDR
A correlation between the deviations from Gaussian statistics and normal diffusion for a 2D liquid was found, which indicates a connection between anomalous diffusion and non-Gaussian statistics, but such a connection is lacking in equilibrium 2D Yukawa liquids, as demonstrated in numerical simulations.

TLDR
At intermediate temperatures, the mean-squared displacement, probability distribution function, and velocity autocorrelation function all indicate superdiffusion; the VACF has a long-time tail; and the PDF indicates no Lévy flights. Expand

Test of the Stokes-Einstein relation in a two-dimensional Yukawa liquid.
TLDR
The Stokes-Einstein relation, Deta proportional k(B)T, was found to be violated near the disordering transition; under these conditions collective particle motion exhibits dynamical heterogeneity; at slightly higher temperatures, however, the Stokes and Einstein relation is valid. Expand
