Micromotors Driven by Spin-Orbit Interaction of Light: Mimicking Planetary Motion at the Microscale
Ram Nandan Kumar, Jeeban Kumar Nayak, Subhasish Dutta Gupta +2
We introduce a new class of optical micromotors driven by the spin-orbit interaction of light and spin-driven fluid flows leading to simultaneous rotation and revolution of the mic…

Probing inhomogeneous and dual asymmetric angular momentum exploiting spin-orbit interaction in tightly focused vector beams in optical tweezers
Ram Nandan Kumar, Jeeban Kumar Nayak, Anand Dev Ranjan +3
The spin-orbit interaction (SOI) of light generated by tight focusing in optical tweezers has been regularly employed in generating angular momentum - both spin and orbital - in tr…
