What does d-wave symmetry tell us about the pairing mechanism?
K. Levin, D. Z. Liu, Jiri Maly
In this paper we argue that d-wave symmetry is a general consequence of superconductivity driven by repulsive interactions. Van Hove (or flat band) effects, deriving from the two d…

An Alternative Route to D-wave Superconductivity: the Charge Channel
Dong-Zi Liu, K. Levin
We demonstrate that a superconducting pairing is naturally associated with the screened Coulomb interaction within the plane of high $T_c…
