Channeling of particles and associated anomalous transport in a two-dimensional complex plasma crystal

Author(s): Cheng-Ran Du, Vladimir Nosenko, Sergey Zhdanov, Hubertus M. Thomas, and Gregor E. Morfill

Implications of the recently discovered effect of channeling of upstream extra particles for transport phenomena in a two-dimensional plasma crystal are discussed. Upstream particles levitated above the lattice layer and tended to move between the rows of lattice particles. An example of heat transp...

Network analysis of three-dimensional complex plasma clusters in a rotating electric field

Author(s): I. Laut, C. Räth, L. Wörner, V. Nosenko, S. K. Zhdanov, J. Schablinski, D. Block, H. M. Thomas, and G. E. Morfill

Network analysis was used to study the structure and time evolution of driven three-dimensional complex plasma clusters. The clusters were created by suspending micron-size particles in a glass box placed on top of the rf electrode in a capacitively coupled discharge. The particles were highly charg...

Evolution of frequency clusters in the naturally occurring dust acoustic wave

Author(s): J. D. Williams

The spatiotemporal evolution of the naturally occurring dust acoustic wave mode is experimentally investigated in a weakly coupled dc glow discharge dusty plasma system over a range of neutral gas pressures through the application of a time-resolved Hilbert Transform. Frequency clusters are observed...

Observation of particle pairing in a two-dimensional plasma crystal

Author(s): S. K. Zhdanov, V. Nosenko, H. M. Thomas, G. E. Morfill, and L. Couëdel

The observation is presented of naturally occurring pairing of particles and their cooperative drift in a two-dimensional plasma crystal. A single layer of plastic microspheres was suspended in the plasma sheath of a capacitively coupled radio-frequency discharge in argon at a low pressure of 1 Pa. ...

Simple estimation of thermodynamic properties of Yukawa systems

Author(s): S. A. Khrapak, A. G. Khrapak, A. V. Ivlev, and G. E. Morfill

A simple analytical approach to estimate thermodynamic properties of model Yukawa systems is presented. The approach extends the traditional Debye-Hückel theory into the regime of moderate coupling and is able to qualitatively reproduce thermodynamics of Yukawa systems up to the fluid-solid phase tr...
