Topological phases of tight-binding trimer lattice in the BDI symmetry class
M Ghuneim, RW Bomantara - Journal of Physics: Condensed …, 2024 - iopscience.iop.org
In this work, we theoretically study a modified Su-Schrieffer-Heeger (SSH) model in which
each unit cell consists of three sites. Unlike existing extensions of the SSH model which are …

Isospectrial reduction of the SSH3 lattice and its bulk-edge correspondence
QH Guo, Y Zhang, XH Wan, LY Zheng - arXiv preprint arXiv:2411.12283, 2024 - arxiv.org
Here, we propose an isospectral reduction (IR) approach for the mapping of a trimer Su-
Schrieffer-Heeger (SSH3) lattice into a simplified two-site model, whose coupling dynamics …
