Observation of the topological soliton state in the Su–Schrieffer–Heeger model
The Su-Schrieffer-Heeger (SSH) model, which captures the most striking transport properties of the conductive organic polymer trans-polyacetylene, provides perhaps the most basic model system supporting topological excitations. The alternating bond pattern of polyacetylene chains is captured by the bipartite sublattice structure of the SSH model, emblematic of one-dimensional chiral symmetric t...
متن کاملDimensionality Effects on the Su-Schrieffer-Heeger Model
A low order diagrammatic study of the dimension dependent Su-SchriefferHeeger model Hamiltonian in the weak electron-phonon coupling regime is presented. Exact computation of both the charge carrier effective mass and the electron spectral function shows that electrons are good quasiparticles in the antiadiabatic limit but new features emerge in the adiabatic and intermediate regime, where the ...
متن کاملPath Integral Methods in the Su-Schrieffer-Heeger Polaron Problem
I propose a path integral description of the Su-Schrieffer-Heeger Hamiltonian, both in one and two dimensions, after mapping the real space model onto the time scale. While the lattice degrees of freedom are classical functions of time and are integrated out exactly, the electron particle paths are treated quantum mechanically. The method accounts for the variable range of the electronic hoppin...
متن کاملSize dependence of second-order hyperpolarizability of finite periodic chains under Su-Schrieffer-Heeger model
– The second hyperpolarizability γN(−3ω;ω,ω, ω) of N double-bond finite chain of trans-polyacetylene is analyzed using the Su-Schrieffer-Heeger model to explain qualitative features of the size-dependence behavior of γN . Our study shows that γN/N is nonmonotonic with N and that the nonmonotonicity is caused by the dominant contribution of the intraband transition to γN in polyenes. Several imp...
متن کاملSpectral Properties of the Su-Schrieffer-Heeger Model
We present a study of the one dimensional Su-Schrieffer-Heeger model Hamiltonian by a diagrammatic perturbative method in the weak electron-phonon coupling regime. Exact computation of both the charge carrier effective mass and the electron spectral function shows that electrons are good quasiparticles in the adiabatic and antiadiabatic limits but novel features emerge in the intermediate regim...
