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…
