Levitated Optomechanics with Spheres of Superfluid Helium

Optomechanics, the study of interactions between light and matter, can be used to make extremely precise measurements. By levitating drops of superfluid helium in a magnetic field under vacuum, we can create an optomechanical system that is isolated from sources of external noise. This system is also capable of deforming its surface from its equilibrium spherical shape and hosting optical whispering gallery modes along the drop's perimeter. Furthermore, using superfluid helium allows us to take advantage of its material properties in our experiments, including its low temperature, its ability to evaporatively cool, its low mechanical loss, and low optical absorption. I will discuss our developments in forming and measuring these drops and plans for further development of this system.
