In this talk, I'm going to discuss our progress on learning how to control these levitated particles in high vacuum conditions, where a feedback cooling is required. I will present our results, which include cooling down the translational motion of the particles down to 20K and study of the effect of stray electric fields on the efficiency of the feedback cooling. Finally, I'm going to talk about our most recent work on locking nanoplatelets' rotation to an external RF fields, which allows us to tune their spinning frequency as well as the spinning axis orientation. This shows that we are close to having full control over both translational and rotational degrees of freedom for the levitated graphite flakes, which is a crucial condition for further research on levitated 2D materials.
