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 wave amplification and temporal topological state in a genuine photonic time crystal
Jiang Xiong, Xudong Zhang, Longji Duan +6
Photonic time crystals (PTCs) are materials whose dielectric permittivity is periodically modulated in time, giving rise to bandgaps not in energy-as in conventional photonic cryst…
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…
Flatbands from Bound States in the Continuum for Orbital Angular Momentum Localization
Weiwei Zhu, Hongyu Zou, Yong Ge +7
A flatband material is a system characterized by energy bands with zero dispersion, allowing for the compact localization of wavefunctions in real space. This compact localization…
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…
A programmable topological photonic chip
Tianxiang Dai, Anqi Ma, Jun Mao +12
Controlling topological phases of light has allowed experimental observations of abundant topological phenomena and development of robust photonic devices. The prospect of more sop…
Observation of disorder-induced boundary localization
Bing-bing Wang, Zheyu Cheng, Hong-yu Zou +7
Bloch wavefunctions in crystals experience localization within the bulk when disorder is introduced, a phenomenon commonly known as Anderson localization. This effect is considered…
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…
Dirac mass induced by optical gain and loss
Letian Yu, Haoran Xue, Ruixiang Guo +5
Mass is commonly regarded as an intrinsic property of matter, but modern physics reveals particle masses to have complex origins, such as the Higgs mechanism in high-energy physics…
Topological Directional Coupler
Yandong Li, Minwoo Jung, Yang Yu +3
Interferometers and beam splitters are fundamental building blocks for photonic neuromorphic and quantum computing machinery. In waveguide-based photonic integrated circuits, beam-…
