# Symbolic transfer entropy analysis of the dust interaction in the presence of wakefields in dusty plasmas

Author(s): André Melzer and André Schella

The method of symbolic transfer entropy has been applied to analyze the behavior of charged-particle systems under the influence of an ion focus (wakefield) in a dusty plasma. Using long-run experiments under various plasma and trapping conditions, it is revealed from the transfer entropy that infor...

# Wakes in inhomogeneous plasmas

Author(s): Roman Kompaneets, Alexei V. Ivlev, Vladimir Nosenko, and Gregor E. Morfill

The Debye shielding of a charge immersed in a flowing plasma is an old classic problem. It has been given renewed attention in the last two decades in view of experiments with complex plasmas, where charged dust particles are often levitated in a region with strong ion flow. Efforts to describe the ...

# Observations of strong ion-ion correlations in dense plasmasa)

# Stress-induced microcracking and cooperative motion of cold dusty plasma liquids

Author(s): Chi Yang and Lin I

We investigate the microresponse of the quasi-two-dimensional dusty plasma liquid around freezing to the shear force from a laser beam through the center of the liquid cluster. It is found that the cold liquid can be viewed as a patchwork of crystalline ordered domains (CODs) which are solidlike but...

# Mobility in a strongly coupled dusty plasma with gas

Author(s): Bin Liu and J. Goree

The mobility of a charged projectile in a strongly coupled dusty plasma is simulated. A net force F, opposed by a combination of collisional scattering and gas friction, causes projectiles to drift at a mobility-limited velocity up. The mobility μp=up/F of the projectile's motion is obtained. Two re...

# Waves in two-dimensional superparamagnetic dusty plasma liquids

Author(s): Peter Hartmann, Zoltán Donkó, Marlene Rosenberg, and Gabor J. Kalman

Wave dispersion relations in the strongly coupled liquid phase of a two-dimensional system of dust grains interacting via both Yukawa and dipole interactions are investigated. The model system comprises a layer of charged superparamagnetic grains in a plasma in an external, uniform magnetic field B ...
