Topological analysis of the complex SSH model
This paper presents the topological analysis of the complex Su-Schrieffer-Heeger (SSH) model using two methods: Berry phase and topological data analysis. We demonstrate how both methods can effectively generate topological phase diagrams for the model, revealing two distinct regions based on the relative magnitudes of the parameters $|v|$ and $|w|$. Specifically, when $|v| > |w|$, the system is found to be topologically trivial, whereas for $|v| < |w|$, it exhibits topologically non-trivial behaviour. Our results contribute to building the groundwork for topological analysis of more complicated SSH-type models.
