Abstract:
We consider an ideal chain whose ends are fixed without fluctuation at different points, possibly by optical tweezers. We
derive a two-point probability distribution of a corresponding random walk and explicitly calculate the scattering function.
We find that the contour plot of the resulting function shows a kind of normal butterfly pattern, contaminated by wavy texture.
These results are compared with some representative previous models.
