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…

Invariance of the Kohn (sloshing) mode in a conserving theory
M. Bonitz, K. Balzer, R. van Leeuwen
It is proven that the center of mass (COM or Kohn) oscillation of a many-body system in a harmonic trap coincides with the motion of a single particle as long as conserving approxi…

Energy spectrum of strongly correlated particles in quantum dots
K. Balzer, C. Nölle, M. Bonitz +1
The ground state and the excitation spectrum of strongly correlated electrons in quantum dots are investigated. An analytical solution is constructed by exact diagonalization of th…
