Acoustic toroidal vortices with programmable links and knots
Shuai Liu, Xiang-Yuan Xu, Hao Ge +3
Toroidal vortices are three-dimensional torus-shaped wave structures characterized by phase circulation around a closed vortex line. Their toroidal geometry provides a natural foun…
Twistsonics: engineering acoustic topological textures in moire sound lattices
Wen-Yu Wang, Shuai Liu, Xiang-Yuan Xu +4
Moire superlattices formed by twisting periodic systems provide a powerful platform for emergent topological phenomena, but their use for programming real-space topology in acousti…
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…
Shot noise signatures identifying non-Abelian properties of Jackiw-Rebbi zero modes
Haoran Ge, Zhen Chen, Yijia Wu +1
Jackiw-Rebbi zero modes were first proposed in 1976 as topologically protected zero-energy states localized at domain walls in one-dimensional Dirac systems. They have attracted wi…
Full extremal process in four-dimensional membrane model
Hao Ge, Xinyi Li, Jiaxi Zhao
We investigate the extremal process of four-dimensional membrane models as the size of the lattice tends to infinity. We prove the cluster-like geometry of the extreme points a…
Generation of spatiotemporal acoustic vortices with arbitrarily oriented orbital angular momentum
Shuai Liu, Hao Ge, Xiang-Yuan Xu +4
Despite extensive exploration of acoustic vortices carrying orbital angular momentum (OAM), the generation of acoustic vortices with OAM orientations beyond the conventional longit…
Direct measurement of acoustic spectral density and fractional topological charge
Hao Ge, Zi-Wei Long, Xiang-Yuan Xu +5
Local density-of-states (LDOS) is a fundamental spectral property that plays a central role in various physical phenomena such as wave-matter interactions. Here, we report on the d…
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…
Topological Node-Lines in Mechanical Metacrystals
Zhan Xiong, Hai-Xiao Wang, Jinjie Shi +4
Topological acoustic and elastic waves have recently emerged as an exciting interdisciplinary field which is still mainly focused on low-dimensional structures and model systems. H…
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…
Acoustic topological insulator and robust one-way sound transport
Cheng He, Xu Ni, Hao Ge +6
Discovery of novel topological orders of condensed matters is of a significant interest in both fundamental and applied physics due to the associated quantum conductance behaviors…
