Abstract
A unified description of solitons in both charge-density-wave (CDW) and spin-density-wave (SDW) systems is presented within Hartree-Fock theory. Spin-carrying solitons correspond to localized SDW region within a CDW ground state or vice versa. Solitons can have a fractional spin component when the CDW and SDW coexist in the ground state. In particular, a SDW in an odd-order commensurate system must coexist with a CDW and solitons have an irrational spin component.Keywords
