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…

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…
