Spin-dependent localization of helical edge states in a non-Hermitian phononic crystal
Junpeng Wu, Riyi Zheng, Jialuo Liang +5
As a distinctive feature unique to non-Hermitian systems, non-Hermitian skin effect displays fruitful exotic phenomena in one or higher dimensions, especially when conventional top…
Anderson Delocalization in Strongly Coupled Disordered Non-Hermitian Chains
Wei-Wu Jin, Jin Liu, Xin Wang +7
Disorder and non-Hermitian effects together can upend how waves localize. In a 1D disordered chain, the non-Hermitian skin effect (NHSE) can induce Anderson delocalization, defying…
Brillouin Klein space and half-turn space in three-dimensional acoustic crystals
Zhenxiao Zhu, Linyun Yang, Jien Wu +14
The Bloch band theory and Brillouin zone (BZ) that characterize wave behaviors in periodic mediums are two cornerstones of contemporary physics ranging from condensed matter to top…
Topological phononic metamaterials
Weiwei Zhu, Weiyin Deng, Yang Liu +6
The concept of topological energy bands and their manifestations have been demonstrated in condensed matter systems as a fantastic paradigm toward unprecedented physical phenomena…
Observation of exceptional points and skin effect correspondence in non-Hermitian phononic crystals
Qiuyan Zhou, Jien Wu, Zhenhang Pu +5
Exceptional points and skin effect, as the two distinct hallmark features unique to the non-Hermitian physics, have each attracted enormous interests. Recent theoretical works reve…
