Observation of Fully Flat Bands in a Photonic Dipolar Kagome Lattice
Han-Rong Xia, Ziyao Wang, Yunrui Wang +2
Flat bands, characterized by zero group velocity and strong energy localization, enable interaction-enhanced phenomena across both quantum and classical systems. Existing photonic…
Topological Degeneracy Induced by Twisting
Han Peng, Qiang Wang, Meng Xiao +3
In recent years, twisting has emerged as a new degree of freedom that plays an increasingly important role in Bloch bands of various physical systems. However, there is currently a…
A Universal Mirror-stacking Approach for Constructing Topological Bound States in the Continuum
Luohong Liu, Tianzi Li, Qicheng Zhang +2
Bound states in the continuum (BICs) are counter-intuitive localized states with eigenvalues embedded in the continuum of extended states. Recently, nontrivial band topology is exp…
Double-bowl State in photonic Dirac nodal line semimetal
Mengying Hu, Ye Zhang, Xi Jiang +5
The past decade has seen a proliferation of topological materials for both insulators and semimetals in electronic systems and classical waves. Topological semimetals exhibit topol…
Topological dislocation modes in three-dimensional acoustic topological insulators
Liping Ye, Chunyin Qiu, Meng Xiao +4
Dislocations are ubiquitous in three-dimensional solid-state materials. The interplay of such real space topology with the emergent band topology defined in reciprocal space gives…
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…
Higher-order Dirac sonic crystals
Huahui Qiu, Meng Xiao, Fan Zhang +1
Discovering new topological phases of matter is a major theme in fundamental physics and materials science. Dirac semimetal provides an exceptional platform for exploring topologic…
Symmetry-enforced three-dimensional Dirac phononic crystals
Xiangxi Cai, Liping Ye, Chunyin Qiu +4
Dirac semimetals, the materials featured with discrete linearly crossing points (called Dirac points) between four bands, are critical states of topologically distinct phases. Such…
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…
Probing Weyl Physics with One-dimensional Sonic Crystals
Xiying Fan, Chunyin Qiu, Yuanyuan Shen +4
Recently, intense efforts have been devoted to realizing classical analogues of various topological phases of matter. In this Letter, we explore the intriguing Weyl physics by a si…
