Rouse model with fluctuating internal friction
R. Kailasham, Rajarshi Chakrabarti, J. Ravi Prakash
A coarse-grained bead-spring-dashpot chain model with the dashpots representing the presence of internal friction, is solved exactly numerically, for the case of chains with more t…

Wet and dry internal friction can be measured with the Jarzynski equality
R. Kailasham, Rajarshi Chakrabarti, J. Ravi Prakash
The existence of two types of internal friction wet and dry is revisited, and a simple protocol is proposed for distinguishing between the two types and extracting the appropriate…

Rheological consequences of wet and dry friction in a dumbbell model with hydrodynamic interactions and internal viscosity
R. Kailasham, Rajarshi Chakrabarti, J. Ravi Prakash
The effect of fluctuating internal viscosity and hydrodynamic interactions on a range of rheological properties of dilute polymer solutions is examined using a finitely extensible…
