Spatial correlation function G(s) of confined polymer chains varies with sequential interval. (a) Results with radius R = 3 and N = 100.(b) Results with chain stiffness parameter b = 70 and chain length N = 50, 100, and 200, respectively. Each plot has three curves corresponding to channel radius R = 2, 3, and 4.
