    • Probing the sheath electric field using thermophoresis in dusty plasma 

      Land, Victor; Smith, Bernie; Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, 2010-04)
      A self-consistent dusty plasma fluid model has been extended to incorporate all the oble gases as the carrier gas. An analysis of void closure in complex plasma composed of these gases over a wide range of experimental ...
    • 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 ...
