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…
