摘要：Room-temperature-superconducting
T

measured by high pressure in hydrides can be theoretically explained by a Brinkman–Rice (BR)–Bardeen–Cooper–Schrieffer (BCS)
T

combining both the generalized BCS

and the diverging effective mass,

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.
