abstract = {By means of sophisticated Monte Carlo methods, we
investigate the conformational phase diagram of a simple
model for flexible polymers with explicit thickness. The
thickness constraint, which is introduced geometrically via
the global radius of curvature of a polymer conformation,
accounts for the excluded volume of the polymer and induces
cooperative effects supporting the formation of secondary
structures. In our detailed analysis of the temperature and
thickness dependence of the conformational behavior for
classes of short tubelike polymers, we find that known
secondary-structure segments like helices and turns, but
also ringlike conformations and stiff rods are dominant
intrinsic topologies governing the phase behavior of such
cooperative tubelike objects. This shows that the thickness
constraint is indeed a fundamental physical parameter that
allows for a classification of generic polymer structures.
