Probing spin-rotation coupling with gyroscopically stabilized nanoparticles — •Vanessa Wachter and Benjamin A. Stickler — Institute for Complex Quantum Systems, Ulm University, Germany

Nanoscale objects hosting internal magnetic degrees of freedom can exhibit strong signatures of spin-rotation coupling, rendering them attractive for sensing applications and for future quantum tests. We present a theoretical toolbox to describe the quantum dynamics of a gyroscopically stabilized nanodiamond, electrically suspended in a Paul trap, and show how its rotation can be controlled by microwave driving of a single embedded nitrogen vacancy spin. We study potential applications of the spin-rotational interplay for sensing and gyroscopy.
