    • Ion-wake Field inside a Glass Box 

      Chen, Mudi; Dropmann, Michael; Matthews, Lorin; Hyde, Truell W. (Physical Review E, 2016-09)
      The confinement provided by a glass box is proving ideal for the formation of vertically aligned structures and a convenient method for controlling the number of dust particles comprising these dust structures as well as ...
    • The magnetic field inside a protoplanetary disk gap opened by planets of different masses 

      Carballido, Augusto; Matthews, Lorin; Hyde, Truell W. (Monthly Notices of the Royal Astronomical Society, 2017)
      We perform magnetohydrodynamic simulations of protoplanetary disc gaps opened by planets of various masses, with the aim of calculating the strength of the vertical magnetic field threading such gaps. We introduce a ...
    • Mapping of force field in a capacitively driven rf plasma discharge 

      Dropmann, Michael; Chen, Mudi; Sabo, Hannah; Laufer, Rene; Herdrich, Georg; Matthews, Lorin; Hyde, Truell W. (Journal of Plasma Physics, 2016-07)
      In this paper a method is described that allows mapping of the forces acting on dust particles in a GEC reference cell. Monodisperse particles are dropped into the plasma environment and their trajectories are tracked using ...
    • Multipole Expansions of Aggregate Charge: How Far to Go? 

      Matthews, Lorin; Coleman, Douglas A.; Hyde, Truell W. (IEEE Transactions on Plasma Science, 2016-04)
      Aggregates immersed in a plasma or radiative environment will have charge distributed over their extended surface. Previous studies have modeled the aggregate charge using the monopole and dipole terms of a multipole ...
    • Photophoretic Force on Aggregate Grains, Monthly Notices of the Royal Astronomical Society 

      Matthews, Lorin; Kimery, J. B.; Wurm, G.; de Beule, C.; Kuepper, M; Hyde, T. W. (Monthly Notices of the Royal Astronomical Society, 2016-01-21)
      The photophoretic force may impact planetary formation by selectively moving solid particles based on their composition and structure. This generates collision velocities between grains of different sizes and sorts the ...
    • Physical interpretation of the spectral approach to delocalization in infinite disordered systems 

      Kostadinova, Eva; Liaw, Constanze; Matthews, Lorin; Hyde, Truell (Materials Research Express, 2016-12-05)
      In this paper we introduce the spectral approach to delocalization in infinite disordered systems and provide a physical interpretation in context of the classical model of Edwards and Thouless. We argue that spectral ...
    • 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 ...
    • Using Dust as Probes to Determine Sheath Extent and Structure 

      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 ...
