Superconductivity at high temperatures: investigation of quadratic electron-phonon coupling
Conceptual image of the formation of quantum bipolarons. The blue spheres represent the positively charged ions in the material’s lattice and the two red dots are the Cooper pairs. Credit: Pavel A. Volkov. A new study published in Physical Assessment Letters (PRL) investigates the potential of quadratic electron-phonon coupling to enhance superconductivity through the formation … Read more
