  • Title: Coil-globule transition of a single short polymer chain: an exact enumeration study.
    Author: Ponmurugan M, Narasimhan SL, Krishna PS, Murthy KP.
    Journal: J Chem Phys; 2007 Apr 14; 126(14):144906. PubMed ID: 17444742.
    Abstract:
    The authors present an exact enumeration study of short self-avoiding walks in two as well as in three dimensions that addresses the question, "what is the shortest walk for which the existence of all the three scaling regimes--coil, globule, and the theta--could be demonstrated." Even though they could easily demonstrate the coil and the globule phase from free energy considerations, they could demonstrate the existence of a theta temperature only by using a scaling form for the distribution of gyration radius. That even such short walks have a scaling behavior is an unexpected result of this work.
