The Kohn mode for trapped Bose gases within the dielectric formalism
Jürgen Reidl, Gyula Bene, Robert Graham +1
The presence of undamped harmonic center of mass oscillations of a weakly interacting Bose gas in a harmonic trap is demonstrated within the dielectric formalism for a previously i…

Shifts and widths of collective excitations in trapped Bose gases by the dielectric formalism
J. Reidl, A. Csordás, R. Graham +1
We present predictions for the temperature dependent shifts and damping rates. They are obtained by applying the dielectric formalism to a simple model of a trapped Bose gas. Withi…

Finite temperature excitations of Bose gases in anisotropic traps
J. Reidl, A. Csordás, R. Graham +1
The mode frequencies of a weakly interacting Bose gas in a magnetic trap are studied as a function of the anisotropy of the trap. As in earlier works the generalized Hartree-Fock-B…
