Quantum geometric tensor and the topological characterization of the extended Su-Schrieffer-Heeger model

Xiang-Long Zeng, Wen-Xi Lai, Yi-Wen Wei +1

We investigate the quantum metric and topological Euler number in a cyclically modulated Su-Schrieffer-Heeger (SSH) model with long-range hopping terms. By computing the quantum ge…
