Enhancement of Superconductivity near a Nematic Quantum Critical Point
Enhancement of Superconductivity near a Nematic Quantum Critical Point
We consider a low ${T}_{c}$ metallic superconductor weakly coupled to the soft fluctuations associated with proximity to a nematic quantum critical point (NQCP). We show that (1) a BCS-Eliashberg treatment remains valid outside of a parametrically narrow interval about the NQCP, (2) the symmetry of the superconducting state ($d$ wave, …
