Cavity optomechanical systems enable interactions between light and mechanical
resonators, providing a platform both for fundamental physics of macroscopic quantum …

Optical microresonators confine light to a particular microscale trajectory, are exquisitely
sensitive to their microenvironment, and offer convenient readout of their optical properties …

Continuous weak measurement allows localizing open quantum systems in state space and
tracing out their quantum trajectory as they evolve in time. Efficient quantum measurement …

Modern navigation systems integrate the global positioning system (GPS) with an inertial
navigation system (INS), which complement each other for correct attitude and velocity …

Brillouin scattering has applications ranging from signal processing,, sensing and
microscopy to quantum information and fundamental science,. Most of these applications …

Quantized vortices are fundamental to the two-dimensional dynamics of superfluids, from
quantum turbulence to phase transitions. However, surface effects have prevented direct …

We measure the quantum fluctuations of a single acoustic mode in a volume of superfluid
He that is coupled to an optical cavity. Specifically, we monitor the Stokes and anti-Stokes …

Holographic duality provides a description of strongly coupled quantum systems in terms of
weakly coupled gravitational theories in a higher-dimensional space. It is a challenge …

We experimentally study the emergence of microcanonical equilibrium states in the turbulent
relaxation dynamics of a two-dimensional chiral vortex gas. Same-sign vortices are injected …

Cavity optomechanical systems provide powerful platforms to manipulate photons and
phonons, open potential applications for modern optical communications and precise …
