In solid state physics, a bandgap (BG) refers to a range of energies where no electronic
states can exist. This concept was extended to classical waves, spawning the entire fields of …

The field of cavity optomechanics is reviewed. This field explores the interaction between
electromagnetic radiation and nanomechanical or micromechanical motion. This review …

The phonon is the physical particle representing mechanical vibration and is responsible for
the transmission of everyday sound and heat. Understanding and controlling the phononic …

Interfacing a single photon with another quantum system is a key capability in modern
quantum information science. It allows quantum states of matter, such as spin states of …

Topological states of matter are particularly robust, since they exploit global features of a
material's band structure. Topological states have already been observed for electrons …

Optomechanical systems couple light stored inside an optical cavity to the motion of a
mechanical mode. Recent experiments have demonstrated setups, such as photonic crystal …

In this paper, we describe a general optomechanical system for converting photons to
phonons in an efficient and reversible manner. We analyze classically and quantum …

Optomechanical systems offer new opportunities in quantum information processing and
quantum sensing. Many solid-state quantum devices operate at millikelvin temperatures …

We present the fabrication and characterization of an artificial crystal structure formed from a
thin film of silicon that has a full phononic band gap for microwave X-band phonons and a …

One of the major advances needed to realize all-optical information processing of light is the
ability to delay or coherently store and retrieve optical information in a rapidly tunable …
