Room-temperature-superconducting Tc 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 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.

Automated summary

Room-temperature superconductivity in hydrides measured under high pressure can be theoretically explained by combining the generalized BCS T-c and the diverging effective mass in the Brinkman-Rice (BR)-Bardeen-Cooper-Schrieffer (BCS) model. The transition from the on-site Coulomb interaction in a correlated metal to the interaction in the superconducting state can lead to superconductivity induced by volume contraction caused by high pressure or low temperature.
