Journal ArticleDOI
Dust Coulomb balls: three-dimensional plasma crystals.
TL;DR: First experimental investigations of spherical three-dimensional plasma crystals consisting of hundreds or thousands of micrometer-sized polymer particles suspended in a radio-frequency gas discharge are described.
Journal ArticleDOI
Structural Properties of Screened Coulomb Balls

TL;DR: While the normalized shell radii are found to be independent of shielding, the shell occupation numbers are sensitive to screening and are quantitatively explained by an isotropic Yukawa model.
Journal ArticleDOI
Confinement of Coulomb balls
TL;DR: In this article, a model for the confinement of the recently discovered Coulomb balls is proposed, which considers thermophoretic, ion-drag, and electric field forces, and shows excellent agreement with the observations.
Journal ArticleDOI
Classical and quantum Coulomb crystals
Michael Bonitz,Patrick Ludwig,H. Baumgartner,Christian H.C.A. Henning,A. Filinov,Dietmar Block,O. Arp,A. Piel,S. Käding,Yu. B. Ivanov,André Melzer,Holger Fehske,Vladimir Filinov +12 more
TL;DR: In this article, Coulomb (Wigner) crystallization phenomena are reviewed focusing on one-component non-neutral plasmas in traps and on macroscopic two-component neutral plasms.
Journal ArticleDOI
Obliquely propagating dust-density plasma waves in the presence of an ion beam.
TL;DR: A model for dust-density waves propagating at an arbitrary angle with respect to the ion-flow direction is presented, which explains the preference for oblique or parallel modes as a function of ion velocity.
