Description |
We consider a single Rouse polymer chain in two dimensions in the presence of a transverse shear flow along the x direction and calculate the persistence probability P-0(t) that the x coordinate of a bead in the bulk of the chain does not return to its initial position up to time t. We show that the persistence decays at late times as a power law P-0(t) similar to t(-theta) with a nontrivial exponent theta. The analytical estimate of theta=0.359 . . . obtained using an independent interval approximation is in excellent agreement with the numerical value theta approximate to 0.360 +/- 0.001.
