- Abstract
- Room-temperature-superconducting Tc measured by high pressure in hydrides can be theoretically explained by a Brinkman?밨ice (BR)?밄ardeen?밅ooper?밪chrieffer (BCS) Tc combining both the generalized BCS Tc and the diverging effective mass, m*/m = 1/(1혻?닋혻(U/Uc)2), with the on-site Coulomb interaction U in the BR picture. A transition from U in a correlated metal of the normal state to Uc in the superconducting state can lead to superconductivity, which can be caused by volume contraction induced by high pressure or low temperature.
