Emergence Of Directional Rotation In Optothermally Activated Colloidal System
Rahul Chand, Chaudhary Eksha Rani, Diptabrata Paul +1
We experimentally demonstrate the emergence of directional rotation in thermally active-passive colloidal structures under optical confinement. The observed handedness of rotation…
Modulation of trion and exciton formation in monolayer WS2 by dielectric and substrate engineering
Tamaghna Chowdhury, Diptabrata Paul, Divya Nechiyil +5
Photoluminescence (PL) of transition metal dichalcogenide (TMD) monolayers is strongly influenced by the dielectric environment. The defect states present in the substrate induces…
Optothermal evolution of active colloidal matter in defocused laser trap
Diptabrata Paul, Rahul Chand, G V Pavan Kumar
Optothermal interaction of active colloidal matter can facilitate environmental cues which can influence the dynamics of active soft matter systems. The optically induced thermal e…
Simultaneous detection of spin and orbital angular momentum of light through scattering from a single silver nanowire
Diptabrata Paul, Deepak K Sharma, G V Pavan Kumar
In recent times the spin angular momentum (SAM) and orbital angular momentum (OAM) of light have gained prominence because of their significance in optical communication systems, m…
Mirror-Coupled Microsphere can narrow the Angular distribution of Photoluminescence from WS2 Monolayers
Shailendra K. Chaubey, Sunny Tiwari, Gokul M. A. +3
Engineering optical emission from two dimensional, transition metal dichalcogenides (TMDs) materials such as Tungsten disulphide (WS2) has implications in creating and understandin…
Optothermal pulling, trapping, and assembly of colloids using nanowire plasmons
Vandana Sharma, Sunny Tiwari, Diptabrata Paul +3
Optical excitation of colloids can be harnessed to realize soft matter systems that are out of equilibrium. In this paper, we present our experimental studies on the dynamics of si…
