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…
Self-Organized Bosonic Domain Walls
Xingchuan Zhu, Shiying Dong, Yang Lin +4
Hardcore bosons on honeycomb lattice ribbons with zigzag edges are studied using exact numerical simulations. We map out the phase diagrams of ribbons with different widths, which…
Quantum distance and the Euler number index of the Bloch band in a 1D spin model
Yu-Quan Ma
We study the Riemannian metric and the Euler characteristic number of the Bloch band in a 1D spin model with multi-site spins exchange interactions. The Euler number of the Bloch b…
The Euler Number of Bloch States Manifold and the Quantum Phases in Gapped Fermionic Systems
Yu-Quan Ma, Shi-Jian Gu, Shu Chen +2
We propose a topological Euler number to characterize nontrivial topological phases of gapped fermionic systems, which originates from the Gauss-Bonnet theorem on the Riemannian st…
