Figure 1

(Color online) (a) and (b) show snapshots from simulations of stretching modes A and B, respectively (in the denatured phase). (c) Specific heat vs $T$, for different polymer lengths, for stretching mode A $\left(f=1\right)$. Looking at the peak, from top to bottom, curves correspond to $N=150$, $N=100$, $N=75$, $N=50$, and $N=25$. (d) Same as (c) for mode B $\left(f=2\right)$. Looking at the peak, from top to bottom, curves correspond to $N=150$, $N=100$, $N=75$, $N=50$, and $N=25$. (e) Plot of the Binder cumulants, $V_N$, as a function of $T$, for mode A, and different values of $N$. Looking on the left, from top to bottom, curves correspond to $N=100$, $N=75$, $N=50$, and $N=25$. (f) Same as (e) for mode B. From top to bottom, curves correspond to $N=150$, $N=100$, $N=75$, $N=50$, and $N=25$. (g) Specific heat vs $T$ for $f=0$. Looking at the peak, from top to bottom, curves correspond to $N=100$, $N=75$, $N=50$, and $N=25$. (h) Binder cumulants vs $T$ for $f=0$. From top to bottom, curves correspond to $N=100$, $N=75$, $N=50$, and $N=25$.Reuse & Permissions
