Ambient-Pressure Room-Temperature Superconductivity in Ternary YHf2H24 Nanoribbons Acoustic Phonon Pumping: A Comprehensive Theoretical Prediction

Achieving room-temperature superconductivity in hydrides typically requires prohibitive pressures exceeding 150 GPa to stabilize the hydrogen clathrate structure. Here, we propose a non-equilibrium pathway to stabilize the superconducting phase of Yttrium-Hafnium Hydride (YHf₂H₂₄) at ambient pressure using a resonant acoustic drive. By targeting the hydrogen sublattice with a 45 GHz acoustic standing wave—derived from mass-scaling the acoustic modes of H₂₄ cages—we induce a parametric renormalization of the electron-phonon coupling constant (λ). Theoretical modeling based on the modified Allen-Dynes equation predicts a critical temperature T_c ≈ 298 K (25°C) with a drive amplitude of 7.5%, enabling operation at standard room temperature without any cooling requirements. Furthermore, we calculate the charge transport limits of this dynamically driven state. With a massive superconducting gap Δ ≈ 45 meV (f_gap ≈ 21.8 THz), a single nanoribbon interconnect supports a conservative data rate of 10.93 Tbps, outperforming PCIe 7.0 copper standards by a factor of >80 while eliminating Joule heating. This 'Living Cable' architecture offers a scalable solution for exascale computing and consumer electronics without cryogenic cooling. To ensure robustness, we include detailed derivations, comparisons to recent ternary hydride advances, and discussions on potential experimental challenges, making this prediction consistent within current theoretical frameworks.
