Optical multipolar torque in structured electromagnetic fields: On helicity gradient torque, quadrupolar torque, and spin of the field gradient
Structured light mechanically interacts with matter via optical forces and torques. Optical torque is traditionally calculated via the flux of total angular momentum (AM) into a volume enclosing an object. In the work published in [Phys. Rev. A 92, 043843 (2015)1050-294710.1103/PhysRevA.92.043843],...
