摘要We compare the mechanical properties of two elastic models for a two-dimensional intrinsically
curved semiflexible biopolymer. Model 1 allows a signed curvature and the model 2
allows a positive definite curvature only. We show exactly that these two models have different
ground states. We discretize both models and use the Monte Carlo method to simulate
the models, and find that they have also different mechanical properties at finite temperature.
Under the same force and with the same intrinsic curvature and bending rigidity, the
extension of model 1 is smaller than that of model 2 at low force, but becomes larger at large
force. Moreover, the extension of model 1 undergoes a discontinuous transition when the
intrinsic curvature is sufficient large, but the extension of model 2 is always a smooth concave
function of force, so that there is no phase transition. The difference between the two
models is due to the fact that under external force model 2 disfavors looped configurations
and favors the configurations with moderate extensions.
