  • Simple method to measure the interaction potential of dielectric grains in a dusty plasma 

    Zhang, Zhuanhao; Qiao, Ke; Kong, Jie; Matthews, Lorin; Hyde, Truell (Physics Review E, 2010-09)
    A simple minimally perturbative method is introduced which provides the ability to experimentally measure both the radial confining potential and the interaction potential between two individual dust particles, levitated ...
  • Slow Plastic Deformation (Creep) of 2D Dusty Plasma Solids 

    Hartmann, P.; Kovacs, A. Z.; Douglass, A. M.; Carmona-Reyes, J.; Matthews, L. S.; Hyde, T. W. (Physical Review Letters, 201-07-09)
    We report complex plasma experiments, assisted by numerical simulations, providing an alternative qualitative link between the macroscopic response of polycrystalline solid matter to small shearing forces and the possible ...
  • Vertical Interaction Between Dust Particles Confined in a Glass Box in a Complex Plasma 

    Kong, Jie; Qiao, Ke; Carmona-Reyes, Jorge; Douglass, Angela; Zhang, Zhuanhao; Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, 2013-04)
    In this experiment, falling particle trajectories within and without a glass box placed on the lower electrode in a Gaseous Electronics Conference reference cell are recorded and analyzed, and the electrostatic forces ...
  • 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 ...
