Light incident upon matter exerts a radiation pressure force, a phenomenon that enables applications such as optical tweezers and laser cooling. Typically, the matter that is moved by radiation pressure is treated as a rigid body, yet new physics and applications emerge when considering radiation pressure on elastic bodies. The simplest interaction involves pulses of laser light reflected off...

High-quality factor (high-Q) resonant metasurfaces provide a powerful means of light-matter interaction [1], yet translating these individual resonances into scalable, multifunctional systems remains a significant challenge. Specifically, the characteristic spectral selectivity of high-Q modes, combined with the spatial extent typically required to support nonlocal resonances, often limits the...

Microwave cavity displacement readout provides a powerful route to high-sensitivity mechanical sensing and quantum transduction when the cavity frequency depends quadratically on membrane position. This quadratic response enables quantum non-demolition phonon-number measurements, suppresses linear back-action at symmetry, and provides a route to resolving mechanical energy quanta. We...

The narrowness of the optical transitions of rare-earth-ion dopants makes them highly sensitive probes of their environment. When rare-earth ions are doped into a magnetic crystal, they display an enriched optical spectrum, with features that can only be explained by including the spins of the host crystal in the model. We explored optical absorption spectroscopy of erbium-doped Gd$_2$SiO$_5$,...
