Statistical Properties of a Slit-Confined Wormlike Chain of Finite Length

The wormlike-chain model is commonly used to describe the statistical properties of DNA and liquid-crystal polymers. Following the Green’s function approach, here we present the confinement free energy, compression force, and conformational properties of a wormlike chain in slit confinement over a full range of chain lengths (from rodlike, to semiflexible, and to flexible) and confinement widths (from wide to narrow). Some of these properties...
