Lines of Bound States in the Continuum in a Phononic Crystal Slab
Lin Yang, Riyi Zheng, Sheng Zhang +7
We demonstrate that bound states in the continuum (BICs) form continuous lines along high-symmetry directions of momentum space in a simple phononic crystal slab. Contrary to commo…
Observation of exceptional line semimetal in three-dimensional non-Hermitian phononic crystals
Yejian Hu, Jien Wu, Peidong Ye +6
Non-Hermitian topological phases, which exhibit unique features such as skin effect and exceptional points originated from nontrivial band topologies in complex plane, have attract…
Observation of oriented Landau levels in Berry dipole semimetals
Qingyang Mo, Riyi Zheng, Cuicui Lu +3
Band crossing points, such as Weyl and Dirac points, play a crucial role in the topological classification of materials and guide the exploration of exotic topological phases. The…
Valley edge states as bound states in the continuum
Shunda Yin, Liping Ye, Hailong He +5
Bound states in the continuum (BICs) are spatially localized states with energy embedded in the continuum spectrum of extended states. The combination of BICs physics and nontrivia…
Observation of Higher Order Nodal Line Semimetal in Phononic Crystals
Qiyun Ma, Zhenhang Pu, Liping Ye +6
Higher-order topological insulators and semimetals, which generalize the conventional bulk-boundary correspondence, have attracted extensive research interest. Among them, higher-o…
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…
Observation of quadruple Weyl point in hybrid-Weyl phononic crystals
Li Luo, Weiyin Deng, Yating Yang +4
The discovery of Weyl semimetals opens the door for searching topological semimetals in physical science. The Weyl points are generally recognized as conventional, quadratic, spin-…
