Inhomogeneous spin momentum induced orbital motion of birefringent particles in tight focusing of vector beams in optical tweezers
Ram Nandan Kumar, Sauvik Roy, Anand Dev Ranjan +3
Spin orbit interaction (SOI) due to tight focusing of light in optical tweezers has led to exciting and exotic avenues towards inducing rotation in microscopic particles. However,…

Giant conductance of PSS:PEDOT micro-surfaces induced by microbubble lithography
Anand Dev Ranjan, Rakesh Sen, Sumeet Kumar +5
We provide direct evidence of the effects of interface engineering of various substrates by Microbubble lithography (MBL). We choose a model organic plastic (or polymer) poly(3,4-e…

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…
