Charge and spin dynamics of interacting Fermions in a one dimensional harmonic trap
Lars Kecke, Hermann Grabert, Wolfgang Häusler
We study an atomic Fermi gas interacting through repulsive contact forces in a one dimensional harmonic trap. Bethe-Ansatz solutions lead to an inhomogeneous Tomonaga-Luttinger mod…

Ladder approximation to spin velocities in quantum wires
Lars Kecke, Wolfgang Häusler
The spin sector of charge-spin separated single mode quantum wires is studied, accounting for realistic microscopic electron-electron interactions. We utilize the ladder approximat…
