“…These biopolymers form ring structures under the laser radiation forces. Such kinds of pattern formations have also been observed in trapped liquid crystals [16][17][18][19] and in point-particle plasmas [20][21][22][23][24].…”

Inspired by recent experiments and simulations on pattern formation in biomolecules by optical tweezers, a theoretical description based on the reference interaction site model (RISM) is developed to calculate the equilibrium density profiles of small polyelectrolytes in an external potential. The formalism is applied to the specific case of a finite number of Gaussian and rodlike polyelectrolytes trapped in a harmonic potential. The density profiles of the polyelectrolytes are studied over a range of lengths and numbers of polyelectrolytes in the trap, and the strength of the trap potential. For smaller polymers we recover the results for point charges. In the mean field limit the longer polymers, unlike point charges, form a shell at the boundary layer. When the interpolymer correlations are included, the density profiles of the polymers show sharp shells even at weaker trap strengths. The implications of these results are discussed. * Electronic address: ysjho@apctp.org 1 arXiv:1511.03792v2 [cond-mat.soft]

“…In current experiments on spherical dust crystals performed at the Universities of Kiel and Greifswald [15] typical values of the screening parameter are in the range of 0.6 κ 1.6. While this gives access only to a small part of the analyzed parameters where no re-entrant shell fillings (third anomaly) occur, still the first two effects should be observable.…”

“…Coulomb crystallization also occurs in classical and quantum two-component systems, such as electron-ion or electron-hole plasmas [7,8] or laser-cooled expanding plasmas [9], for a recent overview see [10,11]. Of particular recent interest has been crystallization of charged microspheres in complex plasmas in two dimensions [12]- [14], as well as in three dimensions [15] since here the structure and dynamics of the individual particles is directly visible or recordable by standard CCD cameras, e.g. [16].…”

On the Coulomb-dipole transition in mesoscopic classical and quantum electron-hole bilayers P Ludwig, K Balzer, A Filinov et al. Abstract. Small three-dimensional strongly coupled clusters of charged particles in a spherical confinement potential arrange themselves in nested concentric shells. If the particles are immersed into a background plasma the interaction is screened. The cluster shell configuration is known to be sensitive to the screening strength. With increased screening, an increased population of the inner shell(s) is observed. Here, we present a detailed analysis of the ground state shell configurations and configuration changes in a wide range of screening parameters for clusters with particle numbers N in the range of 11 to 60. We report three types of anomalous behaviors which are observed upon increase of screening, at fixed N or for an increase of N at fixed screening. The results are obtained by means of extensive first principle molecular dynamics simulations.

“…In this article we will focus on stereoscopy. Other techniques that are able to retrieve 3-D particle positions include inline holography (Kroll, Block & Piel 2008), colour-gradient methods (Annaratone et al 2004), scanning video microscopy (Pieper, Goree & Quinn 1996;Arp et al 2004;Samsonov et al 2008), light field imaging with plenoptic cameras (Hartmann, Donko & Donko 2013) or tomographic-PIV (Williams 2011) which, however, will not be reviewed here.…”

The fundamentals of stereoscopy and their application to dusty plasmas are described. It is shown that stereoscopic methods allow us to measure the three-dimensional particle positions and trajectories with high spatial and temporal resolution. The underlying technical implications are presented and requirements and limitations are discussed. The stereoscopic method is demonstrated for dust particles in dust-density waves under microgravity conditions.
