  We present using simple scaling arguments and one step replica symmetry
breaking a theory for the localization of semiflexible polymers in a quenched
random environment. In contrast to completely flexible polymers, localization
of semiflexible polymers depends not only on the details of the disorder but
also on the ease with which polymers can bend. The interplay of these two
effects can lead to the delocalization of a localized polymer with an increase
in either the disorder density or the stiffness. Our theory provides a general
criterion for the delocalization of polymers with varying degrees of
flexibility and allows us to propose a phase diagram for the highly folded
(localized) states of semiflexible polymers as a function of the disorder
strength and chain rigidity.
