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…

Realizing negative index of refraction in an ensemble of ground-state polar molecules with lasers
Dibyendu Sardar, Sauvik Roy, Ghanasyam Remesh +2
We propose a coherent optical method for creating negative refractive index (NRI) for a gaseous ensemble of ground-state polar molecules possessing both permanent electric and magn…
