Multipolar optical binding in focus
Ashutosh Shukla, Sneha Boby, G V Pavan Kumar
The optical binding of gold nanoparticles has conventionally been explored within the Rayleigh limit using dipole approximations. But the field is increasingly focusing on the Mie…
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…
Optothermally Induced Active and Chiral Motion of the Colloidal Structures
Rahul Chand, Ashutosh Shukla, Sneha Boby +1
Artificial soft matter systems have appeared as important tools to harness mechanical motion for microscale manipulation. Typically, this motion is driven either by the external fi…
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…
Opto-thermoelectric trapping of Fluorescent Nanodiamonds on Plasmonic Nanostructures
Ashutosh Shukla, Sunny Tiwari, Ayan Majumder +2
Deterministic optical manipulation of fluorescent nanodiamonds (FNDs) in fluids has emerged as an experimental challenge in multimodal biological imaging. Designing and developing…
First-principle calculations on Li2CuSb: A novel material for lithium-ion batteries
A. Shukla, S. Pandey, H. Pandey
We investigate the Li2CuSb full-Heusler alloy using the first-principles electronic structure calculations and propose the electrochemical lithiation in this alloy. Band structure…
Directing Monolayer Tungsten Disulfide Photoluminescence using a Bent Plasmonic Nanowire on a Mirror Cavity
Shailendra K. Chaubey, Sunny Tiwari, Ashutosh Shukla +3
Designing directional optical antennas without compromising the field enhancement requires specially designed optical cavities. Herein, we report on the experimental observations o…
