Structural transitions of finite spherical Yukawa crystals
H. Baumgartner, D. Asmus, V. Golubnychiy +3
Small three-dimensional strongly coupled clusters of charged particles in a spherical confinement potential arrange themselves in nested concentric shells. If the particles are imm…
Probability of metastable configurations in spherical three-dimensional Yukawa crystals
H. Kählert, P. Ludwig, H. Baumgartner +4
Recently the occurrence probabilities of ground- and metastable states of three-dimensional Yukawa clusters with 27 and 31 particles have been analyzed in dusty plasma experiments…
Existence and Vanishing of the Breathing Mode in Strongly Correlated Finite Systems
C. Henning, K. Fujioka, P. Ludwig +3
One of the fundamental eigenmodes of finite interacting systems is the mode of {\em uniform radial expansion and contraction} -- the ``breathing'' mode (BM). Here we show in a gene…
