    • Agglomeration of Dust Particles in the Lab 

      Matthews, Lorin Swint.; Carmona-Reyes, Jorge; Land, Victor; Hyde, Truell Wayne. (AIP Conference Proceedings, 2011)
      Dust aggregates are formed in a laboratory plasma as monodisperse spheres are accelerated in a self-excited dust density wave. The asymmetric charge on the aggregates causes them to rotate as they interact with the sheath ...
    • Crystallization Dynamics of a Single Layer Complex Plasma 

      Hartmann, Peter; Douglass, Angela Michelle.; Carmona-Reyes, Jorge; Matthews, Lorin Swint.; Hyde, Truell Wayne.; Kovacs, Aniko Zs.; Donko, Zoltan (Physical Review Letters, 2010-09)
      We report a series of complex (dusty) plasma experiments, aimed at the study of the detailed time evolution of the recrystallization process following a rapid quench of a two-dimensional dust liquid. The experiments were ...
    • Dust as probe for horizontal field distribution in low pressure gas discharges 

      Hartmann, Peter; Kovacs, Aniko Zs.; Carmona-Reyes, Jorge; Matthews, Lorin Swint.; Hyde, Truell Wayne. (Plasma Sources Science and Technology, 2014-06-23)
      Using dust grains as probes in gas discharge plasma is a very promising, but at the same time very challenging method, as the individual external control of dust grains has to be solved. We propose and demonstrate the ...
    • The effect of electrode heating on the discharge parameters in complex plasma experiments 

      Land, Victor; Carmona-Reyes, Jorge; Creel, James Ruell.; Schmoke, Jimmy; Cook, Mike; Matthews, Lorin Swint.; Hyde, Truell Wayne. (IOP Publishing, 2011-01-25)
      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 ...
    • Measurement of net electric charge and dipole moment of dust aggregates in a complex plasma 

      Yousefi, Raziyeh.; Davis, Allen; Carmona-Reyes, Jorge; Matthews, Lorin Swint.; Hyde, Truell Wayne. (Physical Review E, 2014-09-02)
      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 ...
    • Mode coupling and resonance instabilities in quasi-two-dimensional dust clusters in complex plasmas 

      Qiao, Ke; Kong, Jie; Carmona-Reyes, Jorge; Matthews, Lorin Swint.; Hyde, Truell Wayne. (American Physical Society, 2014-09-16)
      Small quasi-two-dimensional dust clusters consisting of three to eleven particles are formed in an argon plasma under varying rf power. Their normal modes are investigated through their mode spectra obtained from tracking ...
    • Slow Plastic Deformation (Creep) of 2D Dusty Plasma Solids 

      Hartmann, Peter; Kovacs, Aniko Zs.; Douglass, Angela Michelle.; Carmona-Reyes, Jorge; Matthews, Lorin Swint.; Hyde, Truell Wayne. (Physical Review Letters, 2014-07-09)
      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 ...
    • 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 ...
