Abstract
We study an ensemble of polymers that strongly interact with the surrounding medium. One end of the polymers is fixed, but otherwise there are no restrictions on their possible conformations, allowing also self-crossings. We study in this paper by a Flory argument and by numerical methods the statistical properties of these in the low-temperature limit. We find that these properties strongly depend on the disorder of the surrounding medium, in contrast to the directed polymer case.
