“…A first possible use is the search for new physics beyond the standard model of particle physics. As an alternative approach to colliders pushing the energy frontier, these compact levitodynamics experiments push the sensitivity frontier [139]. They can exploit (i) the high isolation and mass density of levitated particles and (ii) levitation near structured surfaces [131] to detect tiny deviations arising from high-energy physics at short distances [140].…”

The control of levitated nano-and micro-objects in vacuum is of considerable interest, capitalizing on the scientific achievements in the fields of atomic physics, control theory and optomechanics. The ability to couple the motion of levitated systems to internal degrees of freedom, as well as to external forces and systems, provides opportunities for science and technology. Attractive research directions, ranging from fundamental quantum physics to commercial sensors, have been unlocked by the many recent experimental achievements, including motional ground-state cooling of an optically levitated nanoparticle. We review the status, challenges and prospects of levitodynamics, the mutidisciplinary research devoted to understanding, controlling, and using levitated nano-and micro-objects in vacuum.

“…Providing efficient isolation from the environment, optical levitation in vacuum has proven to be an excellent system for investigations of quantum physics at the mesoscale [1][2][3] , for the tests of fundamental physical laws and weak forces sensing 4 , and a unique testbed for stochastic thermodynamics 5 . These exciting developments lie in the ability to control the particle's dynamics finely.…”

The Brownian motion of a particle hotter than its environment is an iconic out-of-equilibrium system. Its study provides valuable insights into nanoscale thermal effects. Notably, it supplies an excellent diagnosis of thermal effects in optically levitated particles, a promising platform for force sensing and quantum physics tests. Thus, understanding the relevant parameters in this effect is critical. In this context, we test the role of particle's shape and material, using optically levitated nanodiamonds hosting NV centers to measure the particles' internal temperature and center-of-mass dynamics. We present a model to assess the nanodiamond internal temperature from its dynamics, adaptable to other particles. We also demonstrate that other mechanisms affect the nanodiamond dynamics and its stability in the trap. Finally, our work, by showing levitating nanodiamonds as an excellent tool for studying nano-thermal effects, opens prospects for increasing the trapping stability of optically levitated particles.

“…The promises of this schemes have been supported by recent experiments that reported trapped particles cooled to the quantum regime [7][8][9][10]. Active development of force sensors are in progress and tests of various models of fundamental physics have also been proposed using various platforms [11][12][13]. To push these developments further and to enable operate the mechanical oscillator in the quantum regime, coupling the dynamics of the levitated system to a single intrinsically quantum system, such as ions, atoms, or artificial atoms, has been envisioned [14,15].…”

Controlling the motion of macroscopic oscillators in the quantum regime has been the subject of intense research in recent decades. In this direction, opto-mechanical systems, where the motion of micro-objects is strongly coupled with laser light radiation pressure, have had tremendous success. In particular, the motion of levitating objects can be manipulated at the quantum level thanks to their very high isolation from the environment under ultra-low vacuum conditions. To enter the quantum regime, schemes using single long-lived atomic spins, such as the electronic spin of nitrogen-vacancy (NV) centers in diamond, coupled with levitating mechanical oscillators have been proposed. At the single spin level, they offer the formidable prospect of transferring the spins’ inherent quantum nature to the oscillators, with foreseeable far-reaching implications in quantum sensing and tests of quantum mechanics. Adding the spin degrees of freedom to the experimentalists’ toolbox would enable access to a very rich playground at the crossroads between condensed matter and atomic physics. We review recent experimental work in the field of spin-mechanics that employ the interaction between trapped particles and electronic spins in the solid state and discuss the challenges ahead. Our focus is on the theoretical background close to the current experiments, as well as on the experimental limits, that, once overcome, will enable these systems to unleash their full potential.
