Orbital-Nematic and Two-Fluid Superconductivity in Hole-Doped NdNiO2
Year: 2025
Type: article
Abstract: Based on DFT + DMFT, we investigate the orbital-nematic and s-wave superconducting states of a hole-doped NdNiO2 superconductor. We emphasize the role played by the interorbital proximity effect in determining the orbital-selective electronic state both in the normal and superconducting phases. Specifically, we show how orbital-nematic plus s-wave pairing symmetry acting on the xz orbital might have pronounced effects on proximitized non-superconducting Ni-3d orbitals due to many-particle electron–electron interactions. This work represents a step forward in understanding the emergence of two-fluid superconductivity (with superconducting xz and non-superconducting xy,yz,x2−y2,3z2−r2 channels) in hole-doped NdNiO2 superconductors.
