The magnetic field inside a protoplanetary disk gap opened by planets of different masses
(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 ...
Multipole Expansions of Aggregate Charge: How Far to Go?
(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 ...
Delocalization in infinite disordered two-dimensional lattices of different geometry
(Physical Review B, 2017-12-06)
The spectral approach to infinite disordered crystals is applied to anAnderson-type Hamiltonian to demonstrate the existence of extended states for nonzero disorder in 2D lattices of different geometries. The numerical ...
Mapping of force field in a capacitively driven rf plasma discharge
(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 ...
Ion-wake Field inside a Glass Box
(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 ...
Temperature Measurements of a Dust Particle
(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
(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 ...
Simple experiment on the sputtering rate of solids in gas discharges
(Physics of Plasmas, 2017-06)
We present a very simple and sensitive method to measure the sputtering rate of solid materials in
stationary low-pressure gas discharges. The method is based on the balance of the centrifugal force
and the confinement ...
