Prediction of Room-Temperature Superconductivity in Quasi-Atomic H₂-Type Hydrides at High Pressure.

ABSTRACT: Achieving superconductivity at room temperature (RT) is a holy grail in physics. Recent discoveries on high-T_c superconductivity in binary hydrides H₃S and LaH₁₀ at high pressure have directed the search for RT superconductors to compress hydrides with conventional electron-phonon mechanisms. Here, an exceptional family of superhydrides is predicated under high pressures, MH₁₂ (M = Mg, Sc, Zr, Hf, Lu), all exhibiting RT superconductivity with calculated T_cs ranging from 313 to 398 K. In contrast to H₃S and LaH₁₀, the hydrogen sublattice in MH₁₂ is arranged as quasi-atomic H₂ units. This unique configuration is closely associated with high T_c, attributed to the high electronic densi
