Correction due to the Goldstone mode in neutral BCS superconductors

Tomio Koyama

Research output: Contribution to journalArticlepeer-review


We develop a theory beyond the Hartree-Fock-Bogoliubov approximation for neutral BCS superconductors at T = 0 K. The self-energy correction due to the interaction between the Goldstone boson and the fermions is calculated. The superconducting order is enhanced by this interaction.
