| 英文摘要 | We study the behaviors of mean end-to-end distance and specific heat of a two-dimensional intrinsically curved semiflexible biopolymer with a hard-core excluded volume interaction. We find the mean square end-to-end distance R-N(2) proportional to N-beta at large N, with N being the number of monomers. Both beta and proportional constant are dependent on the reduced bending rigidity kappa and intrinsic curvature c. The larger the c, the smaller the proportional constant, and 1.5 >= beta >= 1. Up to a moderate kappa = kappa(c), or down to a moderate temperature T = T-c, beta = 1.5, the same as that of a self-avoiding random walk, and the larger the intrinsic curvature, the smaller the kappa(c). However, at a large kappa or a low temperature, beta is close to 1, and the conformation of the biopolymer can be more compact than that of a random walk. There is an intermediate regime with 1.5 > beta > 1 and the transition from beta = 1.5 to beta = 1 is smooth. The specific heat of the system increases smoothly with increasing k or there is no peak in the specific heat. Therefore, a nonvanishing intrinsic curvature seriously affects the thermal properties of a semiflexible biopolymer, but there is no phase transition in the system. |
