Charge measurement of nanoparticles in an RF-plasma by IR absorption
Harald Krüger, Elena Thiessen, Franz Xaver Bronold +2
We have performed measurements of the IR absorption of nanoparticles confined in an argon radio-frequency plasma discharge using an FTIR spectrometer. By varying the…
Configurational temperature in dusty plasmas
Michael Himpel, André Melzer
The temperature of a dust ensemble in a dusty plasma is one of its most fundamental properties. Here, we present experiments using the configurational temperature as a for the temp…
Controlling strongly correlated dust clusters with lasers
Hauke Thomsen, Patrick Ludwig, Michael Bonitz +4
The most attractive feature of dusty plasmas is the possibility to create strong correlations at room temperatures. At the same time, these plasmas allow for a precise diagnostics…
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…
