    • Cosmic Dust Aggregation with Stochastic Charging 

      Matthews, L.S.; Shotorban, B.; Hyde, T.W. (Astrophysical Journal, 2013-10-04)
      The coagulation of cosmic dust grains is a fundamental process which takes place in astrophysical environments, such as presolar nebulae and circumstellar and protoplanetary disks. Cosmic dust grains can become charged ...
    • Dust as probe for horizontal field distribution in low pressure gas discharges 

      Hartmann, P.; Kovacs, A. Z.; Carmona-Reyes, J.; Matthews, L.S.; Hyde, T.W. (Plasma Sources Science and Technology, 2014-06-23)
      Using dust grains as probes in gas discharge plasma is a very promising, but at the same time very challenging method, as the individual external control of dust grains has to be solved. We propose and demonstrate the ...
    • Helical Structures in Vertically Aligned Dust Particle Chains in a Complex Plasma 

      Hyde, T. W.; Kong, J.; Matthews, L.S. (Physical Review E, 2013-05-16)
      Self-assembly of structures from vertically aligned, charged dust particle bundles within a glass box placed on the lower, powered electrode of a Gaseous Electronics Conference rf reference cell were produced and examined ...
    • Interaction force in a vertical dust chain inside a glass box 

      Kong, J.; Qiao, K.; Matthews, L.S.; Hyde, T.W. (Physical Review E, 2014-07-31)
      Small number dust particle clusters can be used as probes for plasma diagnostics. The number of dust particles as well as cluster size and shape can be easily controlled employing a glass box placed within a Gaseous ...
    • Mode couplings and resonance instabilities in dust clusters 

      Qiao, Ke; Van Oeveren, E.; Matthews, L.S.; Hyde, T.W. (Physical Review E, 2013-10-16)
      The normal modes for three to seven particle two-dimensional (2D) dust clusters in a complex plasma are investigated using an N-body simulation. The ion wakefield downstream of each particle is shown to induce coupling ...
    • Vertical probe-induced asymmetric dust oscillation in complex plasma 

      Harris, B. J.; Matthews, L.S.; Hyde, T. W. (Physical Review E, 2013-05-24)
      A complex plasma vertical oscillation experiment which modifies the bulk is presented. Spherical, micron-sized particles within a Coulomb crystal levitated in the sheath above the powered lower electrode in a GEC reference ...
