  • Hartmann, P.; Kovacs, A. Z.; Douglass, A. M.; Carmona-Reyes, J.; Matthews, L. S.; Hyde, T. W. (Physical Review Letters, )
    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 ...
  • 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 ...
  • Smith, Bernard; Vasut, John; Matthews, Lorin; Hyde, Truell; Reay, Jerry; Cook, Mike; Schmoke, Jimmy (Advances in Space Research, )
    Dust particles immersed within a plasma environment, such as those in protostellar clouds, planetary rings or cometary environments, will acquire an electric charge. If the ratio of the inter-particle potential energy to ...
  • Barge, Laura; Matthews, Lorin; Hyde, Truell (Advances in Space Research, )
    Initially uncharged grains in space and laboratory plasma environments become charged due to currents driven by potential differences in the dusty plasma. Certain macroscopic effects such as coagulation of smaller grains ...
  • 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 ...
  • 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 ...
  • Boesse, Carolyn; Henry, Michael; Hyde, Truell; Matthews, Lorin (Advances in Space Research, )
    Dust particles immersed within a plasma environment, such as those found in planetary rings or cometary environments, will acquire an electric charge. If the ratio of interparticle potential energy to average kinetic energy ...
  • Matthews, Lorin; Hyde, Truell (Advances in Space Research, )
    Saturn’s dynamic F-Ring still presents a challenge for understanding and explaining the kinematic processes that lead to the changing structure visible in our observations of this ring. This study examines the effect of ...
  • 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; 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; 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 ...
  • Smith, Bernard; Hyde, Truell; Matthews, Lorin; Reay, Jerry; Cook, Mike; Schmoke, Jimmy (Advances in Space Research, )
    In semiconductor manufacturing, contamination due to particulates significantly decreases the yield and quality of device fabrication, therefore increasing the cost of production. Dust particle clouds can be found in almost ...
  • 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 ...
  • Goedheer, Jan Willem; Land, Victor (IOP Publishing, )
    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 ...
  • 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 (WILEY-VCH, )
    In this paper hydrodynamic and kinetic approaches to model low pressure capacitively coupled complex radiofrequency discharges are discussed and applied to discharges under microgravity. Experiments in the PKENefedov reactor ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Land, Victor; Smith, Bernie; Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, )
    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 ...
