    • 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 ...
    • Transforming teacher pedagogy to maximize 21st century skills through the learning environment 

      Attai, Shanna L., 1987-; Carmona Reyes, Jorge; Davis, John; York, Judy; Ranney, Kerri; Ratliff, Lauren; Hyde, Truell (2020-01-24)
      As schools redesign learning environments and equip classrooms with flexible furniture, it is imperative to examine this impact on teacher pedagogy and student learning. We investigated if classrooms equipped with flexible ...
    • Transport properties of disordered 2D complex plasma crystal 

      Kostadinova, Eva Georgieva, 1992-; Guyton, Forrest.; Cameron, Adam; Busse, Kyle; Liaw, Constanze.; Matthews, Lorin Swint.; Hyde, Truell Wayne. (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 ...
    • Two-dimensional and three-dimensional Coulomb clusters in parabolic traps 

      Myasnikov, M.; D'yachkov, L.; Petrov, O.; Hyde, Truell Wayne.; Kong, Jie; Matthews, Lorin Swint. (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 ...
    • Using Dust as Probes to Determine Sheath Extent and Structure 

      Douglass, Angela Michelle.; 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 ...
    • Vertical Interaction Between Dust Particles Confined in a Glass Box in a Complex Plasma 

      Kong, Jie; Qiao, Ke; Carmona-Reyes, Jorge; Douglass, Angela Michelle.; Zhang, Zhuanhao.; Matthews, Lorin Swint.; Hyde, Truell Wayne. (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, Brandon Joseph.; Matthews, Lorin Swint.; Hyde, Truell Wayne. (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 Swint.; Hyde, Truell Wayne. (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 ...
