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…
Active microrheology to determine viscoelastic parameters of Stokes-Oldroyd B fluids using optical tweezers
Shuvojit Paul, Avijit Kundu, Ayan Banerjee
We use active microrheology to determine the frequency dependent moduli of a linear viscoelastic fluid in terms of the polymer time constant (), and the polymer () and solv…
A quantitative analysis of the emergence of memory in the viscously coupled dynamics of colloids
Shuvojit Paul, Randhir Kumar, Ayan Banerjee
We provide a quantitative description of the evolution of memory from the apparently random Markovian dynamics of a pair of optically trapped colloidal microparticles in water. The…
Dynamics of hydrodynamically coupled Brownian harmonic oscillators in a Maxwell fluid
Shuvojit Paul
Recently, many interesting features of the hydrodynamically coupled motions of the Brownian particles in a viscous fluid have been reported which are impossible for the uncoupled m…
Direct verification of the fluctuation-dissipation relation in viscously coupled oscillators
Shuvojit Paul, Abhrajit Laskar, Rajesh Singh +3
The fluctuation-dissipation relation, a central result in non-equilibrium statistical physics, relates equilibrium fluctuations in a system to its linear response to external force…
