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…
Double magnetic resonance and spin anisotropy in Fe-based superconductors due to static and fluctuating antiferromagnetic orders
Weicheng Lv, Adriana Moreo, Elbio Dagotto
Motivated by recent neutron scattering experiments in Fe-based superconductors, we study how the magnetic resonance in the superconducting state is affected by the simultaneous pre…
-like pairing states in two-leg ladder iron superconductors
Weicheng Lv, Adriana Moreo, Elbio Dagotto
Motivated by the recent report of superconductivity in Fe-based ladder materials, we study the pairing state of a multi-orbital t-J model defined on two-leg ladders using the stand…
Elementary Excitations due to Orbital Degrees of Freedom in Iron Based Superconductors
Wei-Cheng Lee, Weicheng Lv, Hamood Z. Arham
One central issue under intense debate in the study of the iron based superconductors is the origin of the structural phase transition that changes the crystal lattice symmetry fro…
