Topological bound states in interacting Su-Schrieffer-Heeger rings
A. M. Marques, R. G. Dias
We study two-particle states in a Su-Shrieffer-Heeger (SSH) chain with periodic boundary conditions and nearest-neighbor (NN) interactions. The system is mapped into a problem of a…
Notes on the Kitaev \leftrightarrow Tight-binding correspondence
Rui Carlos Andrade Martins, Anselmo Miguel Magalhães Marques, Ricardo Assis Guimarães Dias
In this project, we study the properties of a non-trivial topological system which exhibits localized edge states. In our study, we adress the Kitaev chain, a one-dimensional chain…
Generalization of Zak's phase for lattice models with non-centered inversion symmetry axis
A. M. Marques, R. G. Dias
We show how the presence of inversion symmetry in a one-dimensional (1D) lattice model is not a sufficient condition for a quantized Zak's phase. This is only the case when the inv…
