  • Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, )
    The structure and evolution of aggregate grains formed within a plasma environment are dependent on the charge acquired by the micron-sized dust grains during the coagulation process. The manner in which the charge is ...
  • Ma, Qianyu; Matthews, Lorin; Land, Victor; Hyde, Truell (Astrophysical Journal, )
    The charging of dust grains in astrophysical environments has been investigated with the assumption that these grains are homogeneous spheres. However, there is evidence which suggests that many grains in astrophysical ...
  • Douglass, Angela; Land, Victor; Qiao, Ke; Matthews, Lorin; Hyde, Truell (Physics of Plasmas, )
    Experiments are performed in which dust particles are levitated at varying heights above the powered electrode in a radio frequency plasma discharge by changing the discharge power. The trajectories of particles dropped ...
  • Perry, Jonathan; Matthews, Lorin; Hyde, Truell (IEEE, )
    The interaction between dust grains is an important process in fields as diverse as planetesimal formation or the plasma processing of silicon wafers into computer chips. This interaction depends in large part on the ...
  • Matthews, Lorin; Qiao, Ke; Hyde, Truell (Advances in Space Research, )
    A self-consistent 3D model for a complex (dusty) plasma is used to study the effects of multiple-sized dust grains in a dust crystal. In addition to the interparticle forces, which interact through a Yukawa potential, the ...
  • Matthews, Lorin; Hyde, Truell (New Journal of Physics, )
    This study examines the effect that dipole–dipole charge interactions between fractal aggregates have on the growth of dust grains. Aggregates in a plasma or radiative environment will have charge distributed over their ...
  • Land, Victor; Douglass, Angela; Qiao, Ke; Matthews, Lorin; Hyd, Truell (AIP Conference Proceedings, )
    Using a fluid model, the plasma densities, electron temperature and ion Mach number in front of a powered electrode in different plasma discharges is computed. The dust charge is computed using OML theory for Maxwellian ...
  • Land, Victor; Carmona Reyes, Jorge; Creel, James; Schmoke, Jimmy; Cook, Mike; Matthews, Lorin; Hyde, Truell (IOP Publishing, )
    Thermophoresis is a tool often applied in complex plasma experiments. One of the usual stated benefits over other experimental tools is that electrode temperature changes required to induce thermophoresis do not directly ...
  • Sun, Meihong; Matthews, Lorin; Hyde, Truell (Advances in Space Research, )
    This work investigates the modification of a plasma sheath in a complex plasma due to the presence of dust particles with a specified size distribution. A self-consistent model for the plasma sheath is combined with a ...
  • Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, )
    A numerical model with broad applications to complex (dusty) plasmas is presented. The self-consistent N-body code allows simulation of the coagulation of fractal aggregates, including the charge-dipole interaction of the ...
  • Perry, Jonathan; Kimery, Jesse; Matthews, Lorin; Hyde, Truell (New Journal of Physcis, )
    The coagulation of dust aggregates is an important process in many physical systems such as the Earth’s upper atmosphere, comet tails and protoplanetary discs. Numerical models which study the aggregation in these systems ...
  • Land, Victor; Shen, Erica; Smith, Bernard; Matthews, Lorin; Hyde, Truell (New Journal of Physics, )
    A self-consistent fluid model developed for simulations of microgravity dusty plasma experiments has for the first time been used to model asymmetric dusty plasma experiments in a modified Gaseous Electronics Conference ...
  • Vasut, John; Hyde, Truell; Barge, Laura (Advances in Space Research, )
    Dust particles immersed within a plasma environment, such as those found in planetary rings or comets, will acquire an electric charge. If the ratio of the inter-particle potential energy to average kinetic energy is large ...
  • Land, Victor; Matthews, Lorin; Hyde, Truell; Bolser, Diana (Physics Review E, )
    A self-consistent dusty plasma fluid model has been extended to incorporate all the noble gases as the carrier gas. An analysis of void closure in complex plasma composed of these gases over a wide range of experimental ...
  • Matthews, Lorin; Hayes, Ryan; Freed, Michael; Hyde, Truell (IEEE Transactions on Plasma Science, )
    Planetary formation is an efficient process now thought to take place on a relatively short astronomical time scale. Recent observations have shown that the dust surrounding a protostar emits more efficiently at longer ...
  • Matthews, Lorin; Hyde, Truell (Journal of Physics A, )
    The dynamics of Saturn's F ring have been a matter of curiosity ever since Voyagers 1 and 2 sent back pictures of the ring's unusual features. Some of these images showed three distinct ringlets with the outer two displaying ...
  • Land, Victor; Goedheer, Willem Jan (IOP publishing, )
    Collections of micrometer-sized solid particles immersed in plasma are used to mimic many systems from solid state and fluid physics, due to their strong electrostatic interaction, their large inertia, and the fact that ...
  • Goedheer, Willem Jan; Land, Victor; Venema, Jan (IOP publishing, )
    In this paper hydrodynamic and kinetic approaches to model low-pressure capacitively coupled complex radio-frequency discharges are discussed and applied to discharges under micro-gravity. Complex plasmas contain dust ...
  • Perry, Jonathan; Gostomski, Erwin; Matthews, Lorin; Hyde, Truell (Astronomy & Astrophysics, )
    Context. The coagulation of dust particles is the initial step in planetary formation, with the precursors to planetesimals believed to form via the collisions of micron and submicron sized dust particles in the disk ...
  • Qiao, Ke; Kong, Jie; Zhang, Zhuanhao; Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, )
    The normal modes for horizontal dust particle pairs in a complex plasma are investigated using two methods, a numerical calculation and a molecular dynamics simulation. The ion wakefield downstream of each particle and the ...
