Topological phases, including the conventional first-order and higher-order topological insulators and semimetals, have emerged as a thriving topic in the fields of condensed-matte…
Acoustic corner states in topological insulators with built-in Zeeman-like fields
Xueqin Huang, Jiuyang Lu, Zhongbo Yan +4
The higher-order topological insulators (HOTIs), with such as the topological corner states, emerge as a thriving topic in the field of topological physics. But few connections hav…
Acoustic square-root topological insulators
Mou Yan, Xueqin Huang, Li Luo +3
Square-root topological states are new topological phases, whose topological property is inherited from the square of the Hamiltonian. We realize the first-order and second-order s…

Qiang Wei, Xuewei Zhang, Weiyin Deng +6
The notion of higher-order topological insulators has endowed materials with topological states beyond the first order. Particularly, a three-dimensional (3D) higher-order topologi…

Weiyin Deng, Xueqin Huang, Jiuyang Lu +4
Topologically protected surface modes of classical waves hold the promise to enable a variety of applications ranging from robust transport of energy to reliable information proces…
Ideal type-II Weyl phase and topological transition in phononic crystals
Xueqin Huang, Jiuyang Lu, Feng Li +2
Ideal Weyl points, which are related by symmetry and thus reside at the same frequency, could promote the deep development and utilization of the Weyl physics. Although the ideal t…
Experimental characterization of fragile topology in an acoustic metamaterial
Valerio Peri, Zhi-Da Song, Marc Serra-Garcia +7
Symmetries crucially underlie the classification of topological phases of matter. Most materials, both natural as well as architectured, possess crystalline symmetries. Recent theo…

Jiuyang Lu, Chunyin Qiu, Weiyin Deng +5
Recently, the topological physics in artificial crystals for classical waves has become an emerging research area. In this Letter, we propose a unique bilayer design of sonic cryst…
An effective medium theory for predicting the existence of surface states
Meng Xiao, Xueqin Huang, Anan Fang +1
We build an effective medium theory for two-dimensional photonic crystals comprising a rectangular lattice of dielectric cylinders with the incident electric field polarized along…
Enhancement of polarizabilities of cylinders with cylinder-slab resonances
Meng Xiao, Xueqin Huang, H. Liu +1
If an object is very small in size compared with the wavelength of light, it does not scatter light efficiently. It is hence difficult to detect a very small object with light. We…
Deterministic formation of interface states in some two-dimensional photonic crystals with conical dispersions
Xueqin Huang, Meng Xiao, Zhao-Qing Zhang +1
There is no assurance that interface states can be found at the boundary separating two materials. As a strong perturbation typically favors wave localization, it is natural to exp…
Three dimensional Dirac point at k=0 in photonic and phononic systems
Xueqin Huang, Fengming Liu, C. T. Chan
While "Dirac cone" dispersions can only be meaningfully defined in two dimensional (2D) systems, the notion of a Dirac point can be extended to three dimensional (3D) classical wav…
Dirac Cones at k=0 in Phononic Crystals
Fengming Liu, Yun Lai, Xueqin Huang +1
We show that two-dimensional phononic crystals exhibit Dirac cone dispersion at k=0 by exploiting dipole and quadrupole accidental degeneracy. While the equi-frequency surface of D…
Fractal plasmonic metamaterials for subwavelength imaging
Xueqin Huang, Dexin Ye, Shiyi Xiao +4
We show that a metallic plate with fractal-shaped slits can be homogenitized as a plasmonic metamaterial with plasmon frequency dictated by the fractal geometry. Owing to the all-d…
