Probability density, ρ, of finding the knot at a given position along the polymer under tension, τ = 0.8kBT/σ. For beads 256–511, κi = 1.806kBT ≈ κmin, while for beads 0–255, κi = 0 (×, black), κi = 0.4353kBT (□, red), κi = 0.8706kBT (○, green), or κi = 3.842kBT (Δ, blue). Error bars were estimated by performing three independent repeats of the simulations.
