Micro-OptoMechanical Movements (MOMs) with SoftOxometalates (SOMs): Controlled Motion of Single Soft-Oxometalate Pea-pods Using Exotic Optical Potentials
Basudev Roy, Atharva Sahasrabudhe, Bibudha Parasar +4
An important challenge in the field of materials design and synthesis is to deliberately design mesoscopic objects starting from well-defined precursors and inducing directed movem…
Controlled transportation of mesoscopic particles by enhanced spin orbit interaction of light in an optical trap
Basudev Roy, Nirmalya Ghosh, Subhasish Dutta Gupta +3
We study the effects of the spin orbit interaction (SOI) of light in an optical trap and show that the propagation of the tightly focused trapping beam in a stratified medium can l…
High flux cold Rubidium atomic beam for strongly coupled Cavity QED
Basudev Roy, Michael Scholten
This paper presents a setup capable of producing a high-flux continuous beam of cold rubidium atoms for cavity QED experiments in the regime of strong coupling. A 2 MOT, load…
Probing the dynamics of an optically trapped particle by phase sensitive back focal plane interferometry
Basudev Roy, Sambit Bikas Pal, Arijit Haldar +3
The dynamics of an optically trapped particle are often determined by measuring intensity shifts of the back-scattered light from the particle using position sensitive detectors. W…
