Effect of Fluctuations on the Freezing of a Colloidal Suspension in an External Periodic Potential
J. Chakrabarti, Supurna Sinha
We incorporate the effects of fluctuations in a density functional analysis of the freezing of a colloidal liquid in the presence of an external potential generated by interfering…
Dynamics of Vibrated Grains
Abhishek Dhar, Supurna Sinha
We study number density distribution and the behavior of time correlation functions in the density of grains for a quasi-two dimensional system of vibrated grains. We study the sys…
Onset of Shear Waves In A Bacterial Bath: A Novel Effect
Supurna Sinha
Recent experiments on particle diffusion in bacterial baths indicate the formation of correlated structures in the form of bacterial swirls. Here we predict that such a structural…
Biopolymer Elasticity
Supurna Sinha
In recent years molecular elasticity has emerged as an active area of research: there are experiments that probe mechanical properties of single biomolecules such as DNA and Actin,…
