Phase theory and critical exponents for the Tomonaga-Luttinger model with harmonic confinement
Gao Xianlong, W. Wonneberger
A phase operator formulation for a recent model of interacting one-dimensional fermions in a harmonic trap is developed. The resulting theory is similar to the corresponding approa…

Friedel oscillations in a gas of interacting one-dimensional fermionic atoms confined in a harmonic trap
S. N. Artemenko, Gao Xianlong, W. Wonneberger
Using an asymptotic phase representation of the particle density operator in the one-dimensional harmonic trap, the part which describes the Friedel oscill…

Local Impurity Phase Pinning and Pinning Force in Charge Density Waves
A. Kobelkov, F. Gleisberg, W. Wonneberger
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…
