title: Partition function zeros and finite size scaling of helix-coil transitions in a polypeptide.
abstract: We report on multicanonical simulations of the helix-coil transition of a polypeptide. The nature of this transition was studied by calculating partition function zeros and the finite size scaling of various quantities. New estimates for critical exponents are presented.
