-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…
Phonons and magnetism of kagome FeGe probed by nuclear resonant scattering
Yu Tang, Saizheng Cao, Sijie Xu +6
Kagome FeGe hosts a charge-density wave (CDW) that strongly interplays with antiferromagnetic order. Here, we report Fe nuclear resonant scattering measure…
Quasi-one-dimensional spin excitations in the iron pnictide NaFeCuAs
Yifan Wang, David W. Tam, Weiyi Wang +8
Spectroscopic measurements in model one-dimensional (1D) correlated systems offer insights for understanding their two-dimensional counterparts, which include the cuprate and iron…
Linear scaling relation between two-dimensional massless Dirac fermion Fermi velocity and Fe-As bond length in iron arsenide superconductor systems
Chengpu Lv, Jianzhou Zhao, Yueshan Xu +6
Two-dimensional (2D) massless Dirac fermions (MDF), which represent a type of quasi-particles with linear energy-momentum dispersions only in 2D momentum space, provide a fertile g…
