Optical Supertorque Induced by Mie-Resonant Modes
Ivan Toftul, Mihail Petrov, Romain Quidant +1
We introduce the concept of resonant optical torque that allows enhancing substantially a transfer of optical angular momentum (AM) of light to a subwavelength particle. We conside…

Acoustic Lateral Recoil Force and Stable Lift of Anisotropic Particles
Mikhail Smagin, Ivan Toftul, Konstantin Y. Bliokh +1
Acoustic forces and torques are of immense importance for manipulation of particles, in particular in biomedical applications. While such forces and torques are well understood for…

Acoustic Radiation Force and Torque on Small Particles as Measures of the Canonical Momentum and Spin Densities
I. D. Toftul, K. Y. Bliokh, M. I. Petrov +1
We examine acoustic radiation force and torque on a small (subwavelength) absorbing isotropic particle immersed in a monochromatic (but generally inhomogeneous) sound-wave field. W…
