Superconductivity in alkali-doped C60

Highlight
• Superconductivity in alkali-doped C60 (A3C60) is well described by an s-wave state produced by phonon mediated pairing.
• Moderate coupling of electrons to high-frequency shape-changing intra-molecular vibrational modes produces transition temperatures up to 33 K in single-phase material.
• The good understanding of pairing in A3C60 offers a paradigm for the development of new superconducting materials.

Superconductivity in alkali-doped C60 (A3C60, A = an alkali atom) is well described by an s-wave state produced by phonon mediated pairing. Moderate coupling of electrons to high-frequency shape-changing intra-molecular vibrational modes produces transition temperatures (Tc) up to 33 K in single-phase material. The good understanding of pairing in A3C60 offers a paradigm for the development of new superconducting materials.
