The electron–phonon interaction is a major factor influencing the competition between
collective instabilities in correlated-electron materials, but its role in driving high-temperature …

In normal metals, macroscopic properties are understood using the concept of
quasiparticles. In the cuprate high-temperature superconductors, the metallic state above …

One of the keys to the high-temperature superconductivity puzzle is the identification of the
