“…1) was observed and attributed to the presence of topological edge states in phase B. The band structures resembled qualitatively those known for the Su-Schrieffer-Heeger (SSH) model [41], originally introduced as a tight-binding model for polyacetylene [42,43] (see Ref. [16] for a modern introduction into the topological aspects of the SSH model).…”

“…The SSH tight-binding Hamiltonian belongs to the wider class of models for dimerized quantum chains [48]. It was originally introduced to describe polyacetylene using a tight-binding description for the p z electrons and elastically coupled CH monomers [41,42]. We are not interested in the ion dynamics (i.e., phonons) and just consider the electronic part of the SSH Hamiltonian for a given ion configuration.…”

“…Since the band widths in the systems studied are comparatively large, the coherence length of electronic excitations is large compared to the lattice parameter and a continuum model is appropriate [ Z ] . The most prominent conjugated polymer studied within these models is trans-polyacetylene which, because of its degenerate ground state, gives rise to localized solitonic defects if charge carriers are introduced to the chain by intercalating reducing or oxidizing agents between the polymer chains [3]. There is a number of conjugated polymers which lacks the degeneracy of the ground state, e.g.…”
