Coupling constants for a degenerate Fermi gas confined to a quasi one-dimensional harmonic trap

Autor: Gleisberg, F., Wonneberger, W.

Publikováno v: J.Phys.B:At.Mol.Opt.Phys.37 (2004) S59-S72

A theory for the coupling constants between spin polarized degenerate fermionic atoms is developed for the case of atoms confined to a quasi one-dimensional harmonic trap. Exploiting the presence of the Fermi edge and the large number of fermions it

Treatment of backscattering in a gas of interacting fermions confined to a one-dimensional harmonic atom trap

Autor: Xianlong, Gao, Gleisberg, F., Lochmann, F., Wonneberger, W.

Publikováno v: Phys. Rev. A 67, 023610 (2003)

An asymptotically exact many body theory for spin polarized interacting fermions in a one-dimensional harmonic atom trap is developed using the bosonization method and including backward scattering. In contrast to the Luttinger model, backscattering

Non-Interacting Fermions in a One-Dimensional Harmonic Atom Trap: Exact One-Particle Properties at Zero Temperature

Autor: Gleisberg, F., Wonneberger, W., Schloeder, U., Zimmermann, C.

Publikováno v: Phys.Rev. A, 63602 (2000)

One-particle properties of non-interacting Fermions in a one-dimensional harmonic trap and at zero temperature are studied. Exact expressions and asymptotic results for large Fermion number N are given for the particle density distribution n_0(z,N).

Local Impurity Phase Pinning and Pinning Force in Charge Density Waves

Autor: Kobelkov, A., Gleisberg, F., Wonneberger, W.

Publikováno v: Eur. Phys. J. 9, 21-27 (1999)

Starting from the static Fukuyama-Lee-Rice equation for a three-dimensional incommensurate charge density wave (CDW) in quasi one-dimensional conductors a solvable model for local phase pinning by impurities is defined and studied. We find that avera
