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…

Spatially resolved spin angular momentum mediated by spin-orbit interaction in tightly focused spinless vector beams in optical tweezers
Ram Nandan Kumar, Sauvik Roy, Subhasish Dutta Gupta +2
We demonstrate an effective and optimal strategy for generating spatially resolved longitudinal spin angular momentum (LSAM) in optical tweezers by tightly focusing first-order azi…
