Rotational Jamming of Plasmonic Optical Matter Driven by Chiral Light
Ashutosh Shukla, Sneha Boby, Rahul Chand +1
Plasmonic Optical matter (OM), composed of optically bound metallic particles, can be rotated by transferring the spin angular momentum (SAM) of chiral light to the assembly. Rotat…
Synchronized motion of gold nanoparticles in an optothermal trap
Ashutosh Shukla, Rahul Chand, Sneha Boby +1
Optical tweezers have revolutionized particle manipulation at the micro- and nanoscale, playing a critical role in fields such as plasmonics, biophysics, and nanotechnology. While…
Optothermal Revolution: Colloids in an Optical Ring Trap
Rahul Chand, Ashutosh Shukla, G V Pavan Kumar
Directional motion is commonly observed in various living active systems, such as bacterial colonies moving through confined environments. In these systems, the dynamics arise from…
Evanescent Optothermoelectric Trapping: Deeper Potentials at a Largescale
Chaudhary Eksha Rani, Rahul Chand, Ashutosh Shukla +1
Surface plasmons (SP) and their mediated effects have been widely used to manipulate micro- and nanoscale objects of dielectric and metallic nature. In this work, we show how SP ex…
