我们预测了一系列不寻常的量子声学现象，这些量子声学现象是由完全可调谐的固态平台中的声-物质相互作用引起的，在这个平台中，钻石中的一组固态自旋与一维光机械晶体中的量子化声波耦合。我们发现，通过使用空间变化的激光驱动器，在光力学相互作用中引入依赖于位置的相位，可以在原位调谐机械能带结构，从而导致非传统的量子声-物质相互作用。我们表明，当自旋与能带共振时，可以发生准手征的声-物质相互作用，可调范围从双向到准单向。当固态自旋频率位于声学带隙内时，我们证明了一种奇异的极化子束缚态的出现，它可以调节长程可调的、奇邻的和复杂的自旋-自旋相互作用。这项工作扩展了目前量子声子学的探索，在量子模拟和量子信息处理中具有广泛的应用前景。
We predict a set of unusual quantum acoustic phenomena resulting from sound-matter interactions in a fully tunable solid-state platform in which an array of solid-state spins in diamond are coupled to quantized acoustic waves in a one-dimensional optomechanical crystal. We find that, by using a spatially varying laser drive that introduces a position-dependent phase in the optomechanical interaction, the mechanical band structure can be tuned in situ, consequently leading to unconventional quantum sound-matter interactions. We show that quasichiral sound-matter interactions can occur, with tunable ranges from bidirectional to quasiunidirectional, when the spins are resonant with the bands. When the solid-state spin frequency lies within the acoustic band gap, we demonstrate the emergence of an exotic polariton bound state that can mediate long-range tunable, odd-neighbor, and complex spin-spin interactions. This work expands the present exploration of quantum phononics and can have wide applications in quantum simulations and quantum information processing.
