Effective interaction potential and superfluid-solid transition of spatially indirect excitons
A. Filinov, P. Ludwig, M. Bonitz +1
Using an adiabatic approximation we derive an effective interaction potentially for spatially indirect excitons. Using this potential and path integral Monte Carlo simulations we s…
Spectral properties of spherically confined dusty plasma crystals
C. Henning, H. Kählert, P. Ludwig +2
A combined theoretical and experimental analysis of the normal modes of three-dimensional spherially confined Yukawa clusters is presented. Particular attention is paid to the brea…
Dynamics of strongly correlated ions in a partially ionized quantum plasma
M. Bonitz, P. Ludwig, J. W. Dufty
A scheme which allows to compute the dynamics of strongly correlated classical ions embedded into a partiallzy ionized quantum plasma by first principles molecular dynamics is pres…
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…
