-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…
Momentum Dependence of the Nematic Order Parameter in Iron-Based Superconductors
H. Pfau, S. D. Chen, M. Yi +11
The momentum dependence of the nematic order parameter is an important ingredient in the microscopic description of iron-based high-temperature superconductors. While recent report…
Dynamic spin-lattice coupling and nematic fluctuations in NaFeAs
Yu Li, 1 Zahra Yamani, 2 Yu Song +14
We use inelastic neutron scattering to study acoustic phonons and spin excitations in single crystals of NaFeAs, a parent compound of iron pnictide superconductors. NaFeAs exhibits…
Robust Upward Dispersion of the Neutron Spin Resonance in the Heavy Fermion Superconductor CeYbCoIn
Yu Song, John Van Dyke, I. K. Lum +10
The neutron spin resonance is a collective magnetic excitation that appears in copper oxide, iron pnictide, and heavy fermion unconventional superconductors. Although the resonance…
Electron doping evolution of the neutron spin resonance in NaFeCoAs
Chenglin Zhang, Weicheng Lv, Guotai Tan +8
Neutron spin resonance, a collective magnetic excitation coupled to superconductivity, is one of the most prominent features shared by a broad family of unconventional superconduct…
