BACKGROUND Levitation of large objects has become a widely used technique in science
and engineering, and the control of levitated nano-and micro-objects in vacuum has gained …

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

Dynamical backaction resulting from radiation pressure forces in optomechanical systems
has proven to be a versatile tool for manipulating mechanical vibrations. Notably, dynamical …

Optomechanics is concerned with the use of light to control mechanical objects. As a field, it
has been hugely successful in the production of precise and novel sensors, the …

Numerous astrophysical and cosmological observations are best explained by the existence
of dark matter, a mass density which interacts only very weakly with visible, baryonic matter …

We construct quantum error-correcting codes that embed a finite-dimensional code space in
the infinite-dimensional Hilbert space of rotational states of a rigid body. These codes, which …

We consider the use of quantum-limited mechanical force sensors to detect ultralight (sub-
meV) dark matter (DM) candidates which are weakly coupled to the standard model. We …

Phonons play a key role in the physical properties of materials, and have long been a topic
of study in physics. While the effects of phonons had historically been considered to be a …

Quantum theory is incredibly successful, explaining the microscopic world with great
accuracy, from the behaviour of subatomic particles to chemical reactions to solid-state …

Frequency combs (FCs)—spectra containing equidistant coherent peaks—have enabled
researchers and engineers to measure the frequencies of complex signals with high …
