The complex Directed Polymer problem CDP is shown to have an analogous interface growth equation which is characterized by an extra singular term. This singular term plays a central role in the rich scaling behaviour of CDP. Even without noise, the system is always driven to chaotic, self-sustained and stationary attractors.
