Levitated Nanoparticles have received much attention for their potential to perform quantum mechanical experiments even at room temperature. However, in the regime where the particle dynamics are purely classical there is a lot of interesting physics that can be explored. Here we review the application of levitated nanoparticles as a new experimental platform to explore stochastic thermodynamics in small systems.

Optomechanics with Levitated Particles.
TLDR
Optomechanics is concerned with the use of light to control mechanical objects, and trapped mesoscopic particles are the paradigmatic system for studying nanoscale stochastic processes, and have already demonstrated their utility in state-of-the-art force sensing.
Stochastic thermodynamics of nonharmonic oscillators in high vacuum.
TLDR
It is shown that the nonequilibrium probability density function for the system's energy is a Maxwell-Boltzmann distribution with a closed form time-dependent effective temperature and fractional degrees of freedom and the solvable model satisfies the Crooks fluctuation theorem, as expected.
