Non-Hermitian edge burst of sound
Hong-Yu Zou, Bing-Bing Wang, Yong Ge +6
Non-Hermitian band topology can give rise to phenomena with no counterparts in Hermitian systems. A well-known example is the non-Hermitian skin effect (NHSE), where Bloch eigensta…
Observation of Embedded Topology in a Trivial Bulk via Projective Crystal Symmetry
Hau Tian Teo, Yang Long, Hong-yu Zou +6
Bulk-boundary correspondence is the foundational principle of topological physics, first established in the quantum Hall effect, where a -dimensional topologically nontrivial bu…
Observation of returning Thouless pumping
Zheyu Cheng, Sijie Yue, Yang Long +6
Introduced by David Thouless in 1983, Thouless pumping exemplifies topological properties in topological systems, where the transported charge is quantized by the Chern number. Rec…
Unsupervised Classification of Non-Hermitian Topological Phases under Symmetries
Yang Long, Haoran Xue, Baile Zhang
The integration of artificial intelligence (AI) into fundamental science has opened new possibilities to address long-standing scientific challenges rooted in mathematical limitati…
Non-Abelian Braiding of Topological Edge Bands
Yang Long, Zihao Wang, Chen Zhang +3
Braiding is a geometric concept that manifests itself in a variety of scientific contexts from biology to physics, and has been employed to classify bulk band topology in topologic…
Unsupervised Learning of Topological Non-Abelian Braiding in Non-Hermitian Bands
Yang Long, Haoran Xue, Baile Zhang
The topological classification of energy bands has laid the groundwork for the discovery of various topological phases of matter in recent decades. While this classification has tr…
