DNA unzipping and the unbinding of directed polymers in a random media
Y. Kafri. Abstract Book of the XXIII IUPAP International Conference on Statistical Physics, Genova, Italy, (9-13 July 2007)
Аннотация
We consider the unbinding of a directed polymer in a random media
from a wall in d=1+1 dimensions and a simple model for DNA
unzipping. We show that the replicated partition function of the
DNA unzipping problem is identical to the replicated
generating function for the distance of the directed polymer from
the wall. In particular this allows us to derive the probability
distribution for finding the directed polymers a distance $z$ from
the wall. The implications of these results for the related
Kardar-Parisi-Zhang equation and the asymmetric exclusion process
are discussed.
