Erratum: Anharmonicity and Universal Response of Linear Carbon Chain Mechanical Properties under Hydrostatic Pressure [Phys. Rev. Lett. 125, 105501 (2020)]

Figure 1

(a) Young’s modulus $E$, (b) strain $ϵ$, and (c) Grüneisen parameter $\gamma$ as a function of $P$ for each LCC. Both $E$ and $\gamma$ follow a $P^{-1}$ universal law, while $ϵ$ follows $P^2$ universal law. data (d) $(\mathrm{\Delta }\omega /\omega )(E/\gamma )=-P$, an important parameter nanometrology, is universal and unified. (a)–(d) the solid lines are experimental data fittings. Insets: (a) shows the $E(P)$ vs $P$ graphic enlarged to highlight the $P\to \infty$ limit. The horizontal dashed lines correspond to the values $E$ (4.60 GPa) for each LLC. (b) shows the evolution of $ϵ$ with relation to the relative changes of $C_1$ with increasing $P$. (c) shows the $\gamma (P)$ vs $P$ graphic zoomed to highlight the $P\to \infty$ limit. The horizontal dashed lines correspond to the values of $\gamma$ calculated with $E=0.3\text{TPa}$ for each LCC [1]. The vertical dashed lines in (a) and (c) stand for $P_c=0.1\text{GPa}$.
