Room-temperature-superconducting T(c) driven by electron correlation

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 inter...

description 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.
