Quantum and Classical Proton Diffusion in Superconducting Clathrate Hydrides 《Phys. Rev. Lett.》

The discovery of near room temperature superconductivity in clathrate hydrides has ignited the search for both higher temperature superconductors and deeper understanding of the underlying physical phenomena. In a conventional electron-phonon mediated picture for the superconductivity for these materials, the high critical temperatures predicted and observed can be ascribed to the low mass of t...
