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…
