Spin resonance mode in d-wave superconductors from quasi-2D to 3D
Date:
- Numerical study of resonance mode for sign-changing d-wave superconductors from 2D (cylindrical Fermi surface) to 3D (corrugated cylindrical Fermi surface with hot lines gradually closing).
- Topology of the hot lines instead of Fermi surface matters for the disappearance of resonance mode.
