  • A Simple Introduction to Particle Physics: Part II Geometric Foundations and Relativity 

    Robinson, Matthew; Ali, Tibra; Cleaver, Gerald (2010-07-09)
    This is the second in a series of papers intended to provide a basic overview of some of the major ideas in particle physics. Part I [40] was primarily an algebraic exposition of gauge theories. We developed the group ...
  • 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 ...
  • Simulation of dust voids in complex plasmas 

    Goedheer, Jan Willem; Land, Victor (IOP Publishing, 2008-11-04)
    In dusty radio-frequency (RF) discharges under micro-gravity conditions often a void is observed, a dust free region in the discharge center. This void is generated by the drag of the positive ions pulled out of the ...
  • 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 ...
  • Two-dimensional and three-dimensional Coulomb clusters in parabolic traps 

    Myasnikov, M.; D'yachkov, L.; Petrov, O.; Hyde, T. W.; Kong., J.; Matthews, L. S. (AIP Publishing, 2014-09-08)
    We consider the shell structure of Coulomb clusters in an axially symmetric parabolic trap exhibiting a confining potential U_c(ρ,z)=(mω^2/2)(ρ^2+αz^2) . Assuming an anisotropic parameter α = 4 (corresponding to experiments ...
  • 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 ...
  • Vibrational Modes and Instabilities of a Dust Particle Pair in a Complex Plasma 

    Qiao, Ke; Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, 2010-04-10)
    Vibrational modes and instabilities of a dust-particle pair in a terrestrial aboratory complex plasma are investigated by employing an analytical method whereby the plasma wakefield induced by an external electric field ...
