We work in the regime where both the contour length and the persistence length of the helical polymer are much larger than the diameter of the cylinder. In case (i) we calculate the free energy of confinement and interpret it in terms of a wormlike chain in a pore with an effective diameter that depends on the parameters of the helix. In case (ii) we consider the possibility that one end of the helical polymer escapes from the rod and wanders away. The average numbers of turns at which the helix escapes or intersects the rod are measured in the simulations, as a function of the pitch p(o). The behavior for large and small p(o) is explained with simple scaling arguments. 000041514 536__ $$0G:(DE-Juel1)FUEK242$$2G:(DE-HGF)$$aKondensierte Materie$$cM02$$x0 000041514 542__ $$2Crossref$$i2004-11-18$$uhttp://link.aps.org/licenses/aps-default-license 000041514 588__ $$aDataset connected to Web of Science 000041514 650_7 $$2WoSType$$aJ 000041514 7001_ $$0P:(DE-HGF)0$$aBurkhardt, T.
