Simultaneous active and diffusive behaviour of asymmetric microclusters in a photophoretic trap
Anita Pahi, Kirty Ranjan Sahoo, Biswajit Das +2
Active and diffusive motion in Brownian particles are regularly observed in fluidic environments, albeit at different time scales. Here, we experimentally study the dynamics of hig…

A study of the coupled dynamics of asymmetric absorbing clusters in a photophoretic trap
Anita Pahi, Shuvojit paul, Ayan Banerjee
We report a study on the dynamics of absorbing asymmetric carbon clusters trapped by a loosely focused Gaussian beam using photophoretic force. At high laser powers, all the trappe…
