Three-dimensional structure of a string-fluid complex plasma
Three-dimensional structure of complex (dusty) plasmas was investigated under long-term microgravity conditions in the Plasmakristall-4 facility on the International Space Station. The microparticle suspensions were confined in a polarity-switched dc discharge. The experimental results were compared...

| description | Three-dimensional structure of complex (dusty) plasmas was investigated under long-term microgravity conditions in the Plasmakristall-4 facility on the International Space Station. The microparticle suspensions were confined in a polarity-switched dc discharge. The experimental results were compared to the results of the molecular dynamics simulations with the interparticle interaction potential represented as a superposition of isotropic Yukawa and anisotropic quadrupole terms. Both simulated and experimental data exhibited qualitatively similar structural features, indicating the bulk liquid-like order with the inclusion of solid-like strings aligned with the axial electric field. Individual strings were identified and their size spectrum was calculated. The decay rate of the size spectrum was found to decrease with the enhancement of string-like structural features. |
