rotation of a 3-micron polystyrene sphere around an optical nanofiber guiding two counterpropagating elliptically polarized modes, with polarization ellipticities $\sigma_1=\sigma$ and $\sigma_2=-\sigma$ (for the left and right modes, respectively). For $|\sigma|\approx 1$, the particle's trajectory is close to a circle in the transverse plane. The smaller $|\sigma|$, the more distorted the trajectory becomes, because of the axial asymmetry of the intensity distribution around the nanofiber. The optical power is 15 mW in each mode
