a The pressure trend of the averaged electronic density of states at the Fermi level \(N\left({\epsilon }_{F}\right)\) in quantum fluxional LaH9.63 (with distributions and standard deviation of statics shown in Supplementary Fig. 5), and the pressure trend of \(N\left({\epsilon }_{F}\right)\) in static P1-LaH9.63, fcc-LaH10, and C2/m-LaH10. The \(N\left({\epsilon }_{F}\right)\) of LaH9.63 in fcc and C2/m phase estimated using the rigid-band approximation are also shown for comparison. b The pressure trend of Tc in quantum fluxional LaH9.63 calculated based on various Gaussian smearings (σ) of the phonon spectrum \(F\left(\omega \right)\), together with the values measured for LaH9.6 by Drozdov et al.1 and those derived from AD, Migdal–Eliashberg equations (ME), and superconducting DFT (SCDFT) for fcc-LaH10 by Errea et al.16. Fitted lines are shown to guide the sight.
