Quantifying the role of antiferromagnetic fluctuations in the superconductivity of the doped Hubbard model
Superconductivity arises from the pairing of charge- e electrons into charge-2 e bosons—called Cooper pairs—and their condensation into a coherent quantum state. The exact mechanism by which electrons pair up into Cooper pairs in high-temperature superconductors is still not understood. One of the p...
