Low-Frequency Low-Reflection Bidirectional Sound Insulation Tunnel with Ultrathin Lossy Metasurfaces
Applied Sciences, 2022 We report both numerical and experimental constructions of a tunnel structure with low-frequency low-reflection bidirectional sound insulation (BSI). The designed tunnel was constructed from a pair of lossy acoustic metasurfaces (AMs), which consists of ...

Advanced Functional Materials, EarlyView.The THz drive of the Mott insulating state of a rare‐earth nickelate induces instantaneous insulator‐metal transition via quantum tunneling of valence electrons across the bandgap. This transition is pure electronic and highly non‐thermal, which may find its applications in ultrafast opto‐electronics with enhanced performance and minimal device size ...

A Surface Acoustic Wave based Single Photon Shifter for Solid-state Sources
, 2023 Controlling the frequency of nonclassical light is indispensable for implementing quantum computation, communication and bridging various quantum systems. However, frequency-shift devices for solid state single-photon sources that are easy to integrate are practically absent.
