A stochastic heat engine driven using a nonlinear protocol
Amrutayani Panda, Biswajit Das, Shuvojit Paul +2
A colloidal particle confined in a time-dependent optical trap can function as a microscopic heat engine, with optimization strategies playing a crucial role in enhancing its perfo…
Decoding active force fluctuations from spatial trajectories of active systems
Anisha Majhi, Biswajit Das, Subhadeep Gupta +4
Mesoscopic active systems exhibit various unique behaviours - absent in passive systems - due to the forces generated by the corresponding constituents by converting their availabl…
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…
Irreversibility of mesoscopic processes with hydrodynamic interactions
Biswajit Das, Sreekanth K Manikandan, Shuvojit Paul +3
Optically confined colloidal particles, when placed in close proximity, form a dissipatively coupled system through hydrodynamic interactions. The role of such interactions influen…
