Superdiffusion in two-dimensional Yukawa liquids.
نویسندگان
چکیده
Superdiffusion of two-dimensional (2D) liquids was studied using an equilibrium molecular dynamics simulation. At intermediate temperatures, the mean-squared displacement, probability distribution function (PDF), and velocity autocorrelation function (VACF) all indicate superdiffusion; the VACF has a long-time tail; and the PDF indicates no Lévy flights. These effects are predicted to occur in 2D dusty plasmas and other 2D liquids that can be modeled with a long-range repulsive potential.

Superdiffusion in quasi-two-dimensional Yukawa liquids.
The emergence and vanishing of superdiffusion in quasi-two-dimensional Yukawa systems are investigated by molecular dynamics simulations. Using both the asymptotic behavior of the mean-squared displacement of the particles and the long-time tail of the velocity autocorrelation function as indicators of superdiffusion, we confirm the existence of a transition from normal diffusion to superdiffus...
متن کاملShear viscosity and diffusion motion of two-dimensional dusty plasma liquids
A molecular dynamics method for studying diffusion motion and shear viscosity is presented for two-dimensional (2D) plasma liquids. The calculations obtained by using the mean-squared displacement (MSD), velocity autocorrelation function (VACF) and the shear autocorrelation function indicate that there is a diffusive motion for the lower coupling range of strongly coupled liquid states. In the ...
متن کاملSuperdiffusion of two-dimensional Yukawa liquids due to a perpendicular magnetic field.
Stochastic transport of a two-dimensional (2D) dusty plasma liquid with a perpendicular magnetic field is studied. Superdiffusion is found to occur especially at higher magnetic fields with β of order unity. Here, β = ω(c)/ω(pd) is the ratio of the cyclotron and plasma frequencies for dust particles. The mean-square displacement MSD = 4D(α)t(α) is found to have an exponent α > 1, indicating sup...

is used to distinguish normal diffusion ( 1⁄4 0) from subdiffusion ( < 0) and superdiffusion ( > 0). HPS observed superdiffusion and reported a complicated nonmonotonic dependence of on the potential stiffness 1⁄4 a= , where a is the Wigner-Seitz radius. Here we point out that the behavior ð Þ is, in fact, regular and systematic, whereas the observations of Ref. [1] resulted from a comparison o...
متن کاملSuperdiffusion and non-Gaussian statistics in a driven-dissipative 2D dusty plasma.
Anomalous diffusion and non-Gaussian statistics are detected experimentally in a two-dimensional driven-dissipative system. A single-layer dusty plasma suspension with a Yukawa interaction and frictional dissipation is heated with laser radiation pressure to yield a structure with liquid ordering. Analyzing the time series for mean-square displacement, superdiffusion is detected at a low but st...
