Vectorial Acoustic Multiplexed Holography
Yuan Tian, Hao Ge, Jiangpo Zheng +3
Encoding more information into wave fields is a central goal in imaging, communication, and wave control. Optical holography benefits from polarization multiplexing, but acoustic h…
Non-Hermitian funneling in anisotropic media
Yuan Tian, Nankun Gao, Xiujuan Zhang +2
Non-Hermitian skin effect (NHSE) has emerged as a distinctive phenomenon enabling non-Bloch wave manipulation. However, it has been limited to discrete lattices requiring fine-tune…
Synergy between Spin and Orbital Angular Momenta on a Möbius Strip
Lei Liu, Xiao-Chen Sun, Yuan Tian +3
Spin and orbital angular momenta are fundamental physical characteristics described by polarization and spatial degrees of freedom, respectively. Polarization is a feature of vecto…
Observation of higher-order non-Hermitian skin effect
Xiujuan Zhang, Yuan Tian, Jian-Hua Jiang +2
Hermitian theories play a major role in understanding the physics of most phenomena. It has been found only in the past decade that non-Hermiticity enables unprecedented effects su…
Critical couplings in topological-insulator waveguide-resonator systems observed in elastic waves
Si-Yuan Yu, Cheng He, Xiao-Chen Sun +7
Waveguides and resonators are core components in the large-scale integration of electronics, photonics, and phononics, both in existing and future scenarios. In certain situations,…
Dimensional hierarchy of higher-order topology in three-dimensional sonic crystals
Xiujuan Zhang, Bi-Ye Xie, Hong-Fei Wang +5
Topological phases of matter have been extensively studied for their intriguing bulk and edge properties. Recently, higher-order topological insulators with boundary states that ar…
Symmetry-protected hierarchy of anomalous multipole topological band gaps in nonsymmorphic metacrystals
Xiujuan Zhang, Zhi-Kang Lin, Hai-Xiao Wang +5
Symmetry and topology are two fundamental aspects of many quantum states of matter. Recently, new topological materials, higher-order topological insulators, were discovered, featu…

Experimental Observation of Acoustic Weyl Points and Topological Surface States
Hao Ge, Xu Ni, Yuan Tian +6
Weyl points emerge as topological monopoles of Berry flux in the three-dimensional (3D) momentum space and have been extensively studied in topological semimetals. As the underlyin…
Zone folding induced topological insulators in phononic crystals
Yuanchen Deng, Hao Ge, Yuan Tian +2
This letter investigates a flow-free, pseudospin-based acoustic topological insulator. Zone folding, a strategy originated from photonic crystal, is used to form double Dirac cones…
