WebThe resulting pairing condition is the same as that obtained from the physical constraint of the Anomalous Green’s function.13 For a homogeneous system, choosing a constant pair potential gives rise to the BCS pairing. However, the kernel of the self-consistency equation has not been fixed by the BCS pairing condition. WebThe scattering between two Weyl node plays an important role in pairing mechanism. It is shown that the Fulde-Ferrell-Larkin-Ovchinnikov phase is the ground state if the electrons scattering is dominated by the intra-nodes scattering. On the other hand if the inter-node scattering is strong, the ground state is with the BCS pairing.

WebMay 1, 2004 · It just happened that they used phonons as an example. You could substitute phonons with any bosonic mechanism in that theory and it will still work. In He3, BCS theory works pretty well even when the pairing is due to dipole-dipole interaction. The high-Tc superconductors are of a different beast entirely. porch heaters electric
