High-temperature superconductivity: Exploring quadratic electron-phonon coupling
Conceptual image of the formation of quantum bipolarons. The blue spheres represent the positively charged ions in the lattice of the material and the two red dots are the Cooper pairs. Credit: Pavel A. Volkov. A new study published in Physical review papers (PRL) explores the potential of quadratic electron-phonon coupling to enhance superconductivity through … Read more
