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…

Melting of 2D Coulomb clusters in dusty plasmas
Ryuta Ichiki, Yuriy Ivanov, Matthias Wolter +2
The melting of 2D dust clusters caused by one additional particle in the lower layer has experimentally been observed to undergo a two-step transition, which divides the phase of t…
