摘要
We show that Kramers rate theory gives a straightforward, accurate estimate of the closing time tau(c) of a semiflexible polymer that is valid in cases of physical interest. The calculation also reveals how the time scales of chain relaxation and closing are intertwined, illuminating an apparent conflict between two ways of calculating tau(c) in the flexible limit.
