Peierls instability in 1D Fermi systems with a weak interaction
Krivnov V. Ya. , Ovchinnikov A. A.
The Peierls instability in a ID Fermi system with a weak interaction and a half-filled band is analyzed. The effects of the interaction on the Peierls transition in the model of spinless particles are quite different from the effects in the model of particles with a spin.
