Charge-spin separation in one-dimensional metals and insulators
Johannes Voit
I discuss origin and possible experimental manifestations of charge-spin separation in 1D Luttinger and Luther-Emery liquids, the latter describing 1D Mott and Peierls insulators a…

Spectral properties of Luther-Emery systems
Johannes Voit
We calculate the spectral function of the Luther-Emery model which describes one-dimensional fermions with gapless charge and gapped spin degrees of freedom. We find a true singula…
