Abstract
We extend the 2D wormlike chain model (WLC) for semiflexible polymers to long-range correlated (LRC) heteropolymers. The conjugated contributions of i) the thermal curvature fluctuations characterized by the “dynamic” persistence length ℓdp and ii) the intrinsic LRC curvature disorder of amplitude σo and Hurst exponent H> 1/2, characterized by a “static” persistence length ℓHp, are shown to be described by a continuum of generalized WLC (GWLC) models parametrized by the LRC exponent H. Exact analytic calculations and perturbative analysis are supported by numerical simulations. The relevance of the GWLC model for the description of the elastic properties of genomic DNA is discussed.
