Experimental Measurement of Overlapped Sheaths
Mudi Chen, Michael Dropmann, Ke Qiao +3
Due to the complicated environment of the plasma sheath, it is difficult to experimentally measure plasma characteristics in the narrow geometry where sheaths from opposite boundar…
A machine learning based Bayesian optimization solution to nonlinear responses in dusty plasmas
Zhiyue Ding, Lorin S. Matthews, Truell W. Hyde
Nonlinear frequency response analysis is a widely used method for determining system dynamics in the presence of nonlinearities. In dusty plasmas, the plasma-grain interaction (e.g…
Ion wake induced mode coupling in a horizontal chain in complex plasmas
Ke Qiao, Zhiyue Ding, Jorge R. Carmona +3
Ion wake induced mode coupling is investigated experimentally for a horizontal dust chain formed in a complex plasma, verifying results from previous simulation. A double branch of…
Non-perturbative experiments on plasma-mediated particle interaction and the ion wake potential
Ke Qiao, Zhiyue Ding, Jie Kong +3
A non-perturbative method is introduced to measure the particle-particle interaction strengths and in-situ confinement for a vertically aligned dust particle pair in a complex plas…
Determination of interaction between a dust particle pair in complex plasmas
Ke Qiao, Zhiyue Ding, Jie Kong +3
A non-intrusive method to measure particle interaction using only the thermal motion of the particles is applied to a vertically aligned dust particle pair in a complex plasma. The…
