Scanning tunneling microscopy and kinetic Monte Carlo investigation of Cesium superlattices on Ag(111)
M. Ziegler, J. Kroeger, R. Berndt +2
Cesium adsorption structures on Ag(111) were characterized in a low-temperature scanning tunneling microscopy experiment. At low coverages, atomic resolution of individual Cs atoms…
Linear Response for Confined Particles
Jeffrey Wrighton, James Dufty, Christian Henning +1
The dynamics of fluctuations is considered for electrons near a positive ion or for charges in a confining trap. The stationary nonuniform equilibrium densities are discussed and c…
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…
On the Coulomb-dipole transition in mesoscopic classical and quantum electron-hole bilayers
P. Ludwig, K. Balzer, A. Filinov +2
We study the Coulomb-to-dipole transition which occurs when the separation of an electron-hole bilayer system is varied with respect to the characteristic in-layer distances. A…
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…
