Query: Delocalization transitions of semi-flexible manifolds   Semi-flexible manifolds such as fluid membranes or semi-flexible polymers
undergo delocalization transitions if they are subject to attractive
interactions. We study manifolds with short-ranged interactions by
field-theoretic methods based on the operator product expansion of local
interaction fields. We apply this approach to manifolds in a random potential.
Randomness is always relevant for fluid membranes, while for semi-flexible
polymers there is a first order transition to the strong coupling regime at a
finite temperature.
