Pinning of amplitude solitons in Peierls systems with impurities
The influence of impurities on properties of amplitude solitons in a one-dimensional model of Peierls systems with nearly half-filled bands is investigated. It is shown that there take place a critical dopant concentration and a depinning temperature at which solitons form an unpinned conducting lattice.
