Abstract Room-temperature-superconducting T c measured by high pressure in hydrides can be theoretically explained by a Brinkman–Rice (BR)–Bardeen–Cooper–Schrieffer (BCS) T c combining both the generalized BCS T c and the diverging effective mass, m*/m = 1/(1 − (U/U c )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 U c in the superconducting state can lead to superconductivity, which can be caused by volume contraction induced by high pressure or low temperature. |
