Relaxation behavior of amorphous ices produced with the s ensemble. (A, Left) Average potential energy per particle, in units of $T_{\text{o}}$, as a function of time for the mW model prepared in an ensemble at $s>s^{*}$, $T/T_{\text{o}}=0.8$, $p/p_{\text{o}}=0$, and $t_{\text{obs}}=200\mathrm{\Delta }t$ and evolved with $s=0$, $T/T_{\text{o}}=0.76$, $p/p_{\text{o}}=0$. The dashed black line is an exponential function with characteristic time, $200\mathrm{\Delta }t$. (A, Right) Average pair distribution functions at two indicated points in time. Faint lines show the $g\left(r\right)$ for the alternative solid. (B, Left) Average reduced density as a function of time for the mW model prepared in an ensemble at $s>s^{*}$, $T/T_{\text{o}}=0.76$, $p/p_{\text{o}}=2\times {10}^4$, and $t_{\text{obs}}=200\mathrm{\Delta }t$ and evolved with $s=0$, $T/T_{\text{o}}=0.6$, $p/p_{\text{o}}=5\times {10}^3$. (B, Right) Average pair distribution functions at the two indicated points in time. Faint lines show the $g\left(r\right)$ for the alternative solid.
