High-Sensitivity Accelerometry with a Feedback-Cooled Magnetically Levitated Microsphere
We demonstrate using a large particle trapped in a magneto-gravitational trap as a sensitive accelerometer. The results are comparable to those from a commercial seismometer but with a mass that is four billion times smaller.

Cooling the motion of a silica microsphere in a magneto-gravitational trap in ultra-high vacuum
We demonstrate feedback cooling of the center of mass motion of a silica microsphere in a magneto-gravitational trap to sub-milliKelvin temperatures.

Cooling the motion of diamond nanocrystals in a magneto-gravitational trap in high vacuum
The photoluminescence of trapped diamond nanocrystals is observed while the center of mass motion is cooled by feedback.
