Two-Dimensional Optomechanical Crystal Cavity with High Quantum Cooperativity
Hengjiang Ren, Matthew H. Matheny, Greg S. MacCabe +4
Optomechanical systems offer new opportunities in quantum information processing and quantum sensing. Many solid-state quantum devices operate at millikelvin temperatures -- howeve…
Three-dimensional acoustic double-zero-index medium with a Dirac-like point
Changqing Xu, Guancong Ma, Ze-Guo Chen +4
We report a design and experimental realization of a three-dimensional (3D) acoustic double-zero-index medium (DZIM), whose effective mass density and compressibility are nearly ze…
Phononic bandgap nano-acoustic cavity with ultralong phonon lifetime
Gregory S. MacCabe, Hengjiang Ren, Jie Luo +5
We present measurements at millikelvin temperatures of the microwave-frequency acoustic properties of a crystalline silicon nanobeam cavity incorporating a phononic bandgap clampin…
