-spacing distributions as a probe of nematoelastic response in iron-based superconductors
Wenting Zhang, Ruixian Liu, Tingjun Zhang +14
Electronic nematicity in iron-based superconductors (FeSCs) couples bilinearly to orthorhombic strain, allowing nematic correlations to appear in the lattice response. Here we use…
