Simultaneously cooling the rotational and translational motion of nanoscale dielectrics into the quantum regime is an open task of great importance for sensing applications and quantum superposition tests. Here, we show that the six-dimensional ground state can be reached by coherent-scattering cooling with an elliptically polarized and shaped optical tweezer. We determine the cooling rates and steady-state occupations in a realistic setup and discuss applications for mechanical sensing and…

Theory of nanoparticle cooling by elliptic coherent scattering
Coherent scattering of an elliptically polarised tweezer into a cavity mode provides a promising platform for cooling levitated nanoparticles into their combined rotational and translational quantum
Coherent scattering-mediated correlations between levitated nanospheres
We explore entanglement generation between multiple optically levitated nanospheres interacting with a common optical cavity via the coherent scattering optomechanical interaction. We derive the

ABSTRACT Quantum theory is incredibly successful, explaining the microscopic world with great accuracy, from the behaviour of subatomic particles to chemical reactions to solid-state electronics.
Quantum rotations of nanoparticles
Rotations of microscale rigid bodies exhibit pronounced quantum phenomena that do not exist for their centre-of-mass motion. By levitating nanoparticles in ultra-high vacuum, researchers are

Simultaneous cooling of all six degrees of freedom of an optically levitated nanoparticle by elliptic coherent scattering
We report on strong cooling and orientational control of all translational and angular degrees of freedom of a nanoparticle levitated in an optical trap in high vacuum. The motional cooling and
Surface-induced decoherence and heating of charged particles
Levitating charged particles in ultra-high vacuum provides a preeminent platform for quantum information processing, for quantum-enhanced force and torque sensing, for probing physics beyond the
Interferometric control of nanorotor alignment
The intrinsically non-linear rotation dynamics of rigid bodies offer unprecedented ways for exploiting their quantum motion. In this Letter we devise a rotational analogue of Mach-Zehnder
Stability of a magnetically levitated nanomagnet in vacuum: Effects of gas and magnetization damping
In the absence of dissipation a non-rotating magnetic nanoparticle can be stably levitated in a static magnetic field as a consequence of the spin origin of its magnetization. Here we study the effects
