Hidden topology and strong quantum metric bounds in trivial systems
Chang-An Li, Yulin Qin, Bo Fu +1
The quantum metric integral (QMI) in two-dimensional (2D) systems is conventionally bounded from below by the Chern number. For systems with zero Chern number or identically vanish…
Regularized universal topological markers for Dirac systems
Yulin Qin, Chang-An Li, Jian Li
Topological markers provide an efficient and powerful characterization of topological features of many systems, especially when the translation symmetry is broken. Recently, a univ…
Random-Flux-Induced Transition Sequence between Weak and Strong Topological Phases with Anisotropic Localization Properties
Chang-An Li, Bo Fu, Jian Li +1
We demonstrate that random flux is able to drive nontrivial topological phase transitions, in particular between weak topological insulators (WTIs) and Chern insulators (CIs), illu…
Acoustic Three-dimensional Chern Insulators with Arbitrary Chern Vectors
Yang Linyun, Xi Xiang, Meng Yan +13
The Chern vector is a vectorial generalization of the scalar Chern number, being able to characterize the topological phase of three-dimensional (3D) Chern insulators. Such a vecto…
