Finite-size scaling of helix-coil transitions in poly-alanine studied by   multicanonical simulations
  We report results from multicanonical simulations of poly-alanine. Homopolymers of up to 30 amino acids were considered and various thermodynamic quantities as a function of temperature calculated. We study the nature of the observed helix-coil transition and present estimates for critical exponents.
