Topological phononics
Zeguo Chen, Tiantian Zhang, Xulong Wang +12
Topological phononics extends the foundational concepts of topological condensed matter physics to the realm of lattice vibrations and classical mechanical waves, unlocking robust,…
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…
Acoustic quantum skyrmion-valley Hall effect
Lei Liu, Xiujuan Zhang, Ming-Hui Lu +1
Skyrmions are particle-like topological textures that hold great promise for low-power electronics and wave-based functionalities. Yet their utility is hindered by the lack of robu…
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…
High-Capacity and Real-Time Acoustic Communication by Multiplexing Velocity
Lei Liu, Xiujuan Zhang, Ming-Hui Lu +1
Acoustic communication is indispensable for underwater networks, deep ocean exploration, and biological monitoring, environments where electromagnetic waves become impractical. How…
Skyrmion Molecule Lattices Enabling Stable Transport and Flexible Manipulation
Lei Liu, Xiujuan Zhang, Ming-Hui Lu +1
Skyrmions--topologically protected nanoscale spin textures with vortex-like configurations--hold transformative potential for ultra-dense data storage, spintronics and quantum comp…
