Quantum breathing mode of trapped bosons and fermions at arbitrary coupling
S. Bauch, K. Balzer, C. Henning +1
An analysis of the quantum breathing behavior of few-particle Coulomb systems in one- and two-dimensional harmonic traps is presented. We report the existence of \emph{two independ…
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…
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…
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…
Classical and quantum Coulomb crystals
M. Bonitz, P. Ludwig, H. Baumgartner +10
Strong correlation effects in classical and quantum plasmas are discussed. In particular, Coulomb (Wigner) crystallization phenomena are reviewed focusing on one-component non-neut…
Ground state of a confined Yukawa plasma including correlation effects
C. Henning, P. Ludwig, A. Filinov +2
The ground state of an externally confined one-component Yukawa plasma is derived analytically using the local density approximation (LDA). In particular, the radial density profil…
