Topological inheritance in two-component Hubbard models with single-component Su-Schrieffer-Heeger dimerization

The interplay between interparticle interactions and topological features may result in unusual phenomena. Interestingly, induce an originally trivial system, as we illustrate for the case of a one-dimensional two-component Hubbard model which one component is subjected to Su-Schrieffer-Heeger(SSH) dimerization, whereas other not. We show that due inter-component properties are induced one. Although large inheritance be readily explained by on-site pairing, threshold full occurs at weak interactions, components not yet paired. this discussing both bulk edge properties, well dynamical observables mean chiral displacement charge pumping.
