    • Self-diffusion in two-dimensional quasi-magnetized rotating dusty plasmas 

      Hartmann, Peter; Reyes, J. C.; Kostadinova, E. G.; Matthews, L. S.; Hyde, T. W.; Dzhumagulova, K. N.; Masheyeva, R. U.; Ramazanov, T. S.; Ott, T.; kahlert, H.; Bonitz, M.; Korolov, I.; Donko, Z. (Physical Review E, 2019-01-10)
      The self-diffusion phenomenon in a two-dimensional dusty plasma at extremely strong (effective) magnetic fields is studied experimentally and by means of molecular dynamics simulations. In the experiment the high magnetic ...
    • Simple experiment on the sputtering rate of solids in gas discharges 

      Hartmann, Peter; Carmona-Reyes, Jorge; Korolov, I.; Matthews, Lorin S.; Hyde, Truell W. (Physics of Plasmas, 2017-06)
      We present a very simple and sensitive method to measure the sputtering rate of solid materials in stationary low-pressure gas discharges. The method is based on the balance of the centrifugal force and the confinement ...
    • 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 ...
    • Spectral approach to transport in the two-dimensional honeycomb lattice with substitutional disorder 

      Kostadinova, E. G.; Liaw, C. D.; Hering, A. S.; Cameron, A.; Guyton, F.; Matthews, L. S.; Hyde, T. W. (Physical Review B, 2019-01)
      The transport properties of a disordered two-dimensional (2D) honeycomb lattice are examined numerically using the spectral approach to the 2D percolation problem, characterized by an Anderson-type Hamiltonian. In our ...
    • Temperature Measurements of a Dust Particle 

      Kong, Jie; Qiao, Ke; Matthews, Lorin; Hyde, Truell W. (Journal of Plasma Physics, 2016-09)
      The thermal motion of a dust particle levitated in a plasma chamber is similar to that described by Brownian motion in many ways. The primary difference between a dust particle in a plasma system and a free Brownian particle ...
    • Transport properties of disordered 2D complex plasma crystal 

      Kostadinova, Eva; Guyton, Forest; Cameron, Adam; Busse, Kyle; Liaw, Constanze; Matthews, Lorin S.; Hyde, Truell W. (Contributions to Plasma Physics, 2018-01)
      In this work, we investigate numerically the transport properties of a 2D complex plasma crystal using diffusion of coplanar dust lattice waves. In the limit where the Hamiltonian interactions can be decoupled from the ...

      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 ...

      Douglass, Angela; Land, Victor; Matthews, Lorin; Hyde, Truell W. (Journal of Plasma Physics, 2016-07)
      Two in situ experimental methods are presented in which dust particles are used to determine the extent of the sheath and gain information about the time-averaged electric force profile within a radio frequency (RF) plasma ...
