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…
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…
Simultaneous measurement of mass and rotation of trapped absorbing particles in air
Sudipta K. Bera, Avinash Kumar, Souvik Sil +3
We trap absorbing micro-particles in air by photophoretic forces generated using a single loosely focused Gaussian trapping beam. We measure a component of the radial Brownian moti…
