  • 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 ...
  • Land, Victor; Douglass, Angela; Qiao, Ke; Zhang, Zhuanhao; Matthews, Lorin; Hyde, Truell W. (IEEE Transactions on Plasma Science, )
    The sheath region is probed in different complex plasma experiments using dust particles in addition to the measurement of the optical emission originating from the plasma. The local maximum in the optical emission coincides ...
  • 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 ...
  • Hyde, T. W.; Kong, J.; Matthews, L.S. (Physical Review E, )
    Self-assembly of structures from vertically aligned, charged dust particle bundles within a glass box placed on the lower, powered electrode of a Gaseous Electronics Conference rf reference cell were produced and examined ...
  • 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 ...
  • Kong, J.; Qiao, K.; Matthews, L.S.; Hyde, T.W. (Physical Review E, )
    Small number dust particle clusters can be used as probes for plasma diagnostics. The number of dust particles as well as cluster size and shape can be easily controlled employing a glass box placed within a Gaseous ...
  • Yousefi, Raziyeh; Davis, Allen; Carmona-Reyes, Jorge; Matthews, Lorin; Hyde, Truell (Physical Review E, )
    Understanding the agglomeration of dust particles in complex plasmas requires knowledge of basic properties such as the net electrostatic charge and dipole moment of the dust. In this study, dust aggregates are formed from ...
  • 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 ...
  • Qiao, Ke; Van Oeveren, E.; Matthews, L.S.; Hyde, T.W. (Physical Review E, )
    The normal modes for three to seven particle two-dimensional (2D) dust clusters in a complex plasma are investigated using an N-body simulation. The ion wakefield downstream of each particle is shown to induce coupling ...
  • Matthews, Lorin; Land, Victor; Ma, Qianyu; Perry, Jonathan; Hyde, Truell (AIP Conference Proceedings, )
    The charge on an aggregate immersed in a plasma environment distributes itself over the aggregate’s surface; this can be approximated theoretically by assuming a multipole distribution. The dipole-dipole (or higher order) ...
  • 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 ...
  • 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 ...
  • Dropmann, Michael; Herdrich, Georg; Laufer, Rene; Puckert, Dominik; Fulge, Hannes; Fasoulas, Stefanos; Schmoke, Jimmy; Cook, Mike; Hyde, Truell W. (IEEE Transactions on Plasma Science, )
    As part of the partnership between the Center for Astrophysics, Space Physics and Engineering Research (CASPER) at Baylor University and the Institute of Space Systems (IRS) at the University of Stuttgart, a new design for ...
  • Greenwald, Jared; Pechan, Kristen; Renner, Tim; Ali, Tibra; Cleaver, Gerald
    We present a variation of the NAHE-basis for free fermionic heterotic string mod- els. By rotating some of boundary conditions of the NAHE periodic/anti-periodic fermions {ym, ym, wm, wm,}, for m = 1 to 6, associated with ...
  • Kong, Jie; Hyde, Truell; Matthews, Lorin; Qiao, Ke; Zhang, Zhuanhao (Physical Review E, )
    The oscillation spectrum of a one-dimensional vertical dust string formed inside a glass box on top of the lower electrode in a gaseous electronics conference (GEC) reference cell was studied. A mechanism for creating a ...
