Dimensional hierarchy of topological bound states in the continuum
Shunda Yin, Zhenyu Wang, Liping Ye +5
Bound states in the continuum (BICs), with the ability of trapping and manipulating waves within the radiation continuum, have gained significant attention for their potential appl…
Braiding rule of boundary Majorana-like zero mode
Qiyun Ma, Hailong He, Meng Xiao +1
The study of topological states has become an important topic in both solid-state systems and artificial structures such as photonic crystals and phononic crystals. Among them, Maj…
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…
Acoustic Higher-Order Weyl Semimetal with Bound Hinge States in the Continuum
Zhenhang Pu, Hailong He, Licheng Luo +4
Higher-order topological phases have raised widespread interest in recent years with the occurrence of the topological boundary states of dimension two or more less than that of th…
Acoustic realization of quadrupole topological insulators
Yajuan Qi, Chunyin Qiu, Meng Xiao +3
A quadrupole topological insulator, being one higher-order topological insulator with nontrivial quadrupole quantization, has been intensely investigated very recently. However, th…
Observation of quadratic Weyl points and double-helicoid arcs
Hailong He, Chunyin Qiu, Xiangxi Cai +4
Very recently, novel quasiparticles beyond those mimicking the elementary high-energy particles such as Dirac and Weyl fermions have attracted great interest in condensed matter ph…

Topological negative refraction of surface acoustic waves in a Weyl phononic crystal
Hailong He, Chunyin Qiu, Liping Ye +5
Reflection and refraction occur at interface between two different media. These two fundamental phenomena form the basis of fabricating various wave components. Specifically, refra…
Acoustic Dirac degeneracy and topological phase transitions realized by rotating scatterers

The artificial crystals for classical waves provide a good platform to explore the topological physics proposed originally in condensed matter systems. In this paper, acoustic Dira…
Acoustic one-way mode conversion and transmission by sonic crystal waveguides
Shiliang Ouyang, Hailong He, Zhaojian He +2
We proposed a scheme to achieve one-way acoustic propagation and even odd mode switching in two mutually perpendicular sonic crystal waveguides connected by a resonant cavity. The…
Interplay between Fano resonance and symmetry in non-Hermitian discrete systems
Baogang Zhu, Rong Lü, Shu Chen
We study the effect of PT-symmetric complex potentials on the transport properties of non-Hermitian systems, which consist of an infinite linear chain and two side-coupled defect p…
