Torque-free manipulation of nanoparticle rotations via embedded spins
Torque-free manipulation of nanoparticle rotations via embedded spins
Spin angular momentum and mechanical rotation both contribute to the total angular momentum of rigid bodies, leading to spin-rotational coupling via the Einstein--de Haas and Barnett effects. Here, we show that the revolutions of symmetric nanorotors can be strongly affected by a small number of intrinsic spins. The resulting dynamics …
