Impedance-matched High-Overtone Thickness-Shear Bulk Acoustic Resonators with Scalable Mode Volume
Zi-Dong Zhang, Zhen-Hui Qin, Yi-Han He +5
High overtone bulk acoustic resonators are essential components in microwave signal processing and emerging quantum technologies; however, conventional designs suffer from limited…
Realizing Bloch Dynamics in a Low-Cost Electrically Driven Acoustic Two-Level System
Xiao-Meng Zhang, Guang-Chen He, Zhao-Xian Chen +3
Unlike classical bits that can only occupy one of two discrete states, quantum bits (qubits) can exist in arbitrary coherent superpositions of the ground and excited states. This f…
Direct Measurement of Zak Phase and Higher Winding Numbers in an Electroacoustic Cavity System
Guang-Chen He, Zhao-Xian Chen, Xiao-Meng Zhang +2
Topological phases are states of matter defined by global topological invariants that remain invariant under adiabatic parameter variations, provided no topological phase transitio…
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…
Boundary-induced helical bulk acoustic transport in LiNbO3 thin films
Zhe Li, Zhen-Hui Qin, Shu-Mao Wu +10
We experimentally demonstrate boundary-induced helical bulk states (BI-HBSs) for RF acoustic transport in LiNbO3 thin-film phononic crystals (approximately 175-200 MHz). A boundary…
Zeno Freezing and Anti-Zeno Acceleration of the Dynamic Evolution of Acoustic Topological Boundary States
Xiao-Meng Zhang, Ze-Guo Chen, Guancong Ma +2
Quantum measurements severely disrupt the dynamic evolution of a quantum system by collapsing the probabilistic wavefunction. This principle can be leveraged to control quantum sta…
