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…
Microscopic approach to understand Brownian dynamics in viscoelastic fluid
Shuvojit Paul, Basudev Roy, Ayan Banerjee
We present an entirely microscopic formulation of viscoleasticity of a fluid starting from the microscopic Stokes-Oldroyd B Model assuming instantaneous hydrodynamic friction, and…
