Abstract
- 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 (1D) optomechanical crystal. We find that, by 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 quasi-chiral sound-matter interactions can occur, with tunable ranges from bidirectional to quasi-unidirectional, when the spins are resonant with the bands. When the solid-state spins'frequency lies within the acoustic band-gap, we demonstrate the emergence of an exotic polariton bound state, which 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 simulation and quantum information processing.<br />Comment: 8+11 pages, 4+9 figures, accepted for publication in PRL
