Multiorbital singlet pairing and superconductivity

Emilian M. Nica, Qimiao Si

Recent experiments in multiband Fe-based and heavy-fermion superconductors have challenged the long-held dichotomy between simple - and -wave spin-singlet pairing states. Her…

Spin fluctuation anisotropy as a probe of orbital-selective hole-electron quasiparticle excitations in detwinned Ba(Fe1-xCox)2As2

Long Tian, Panpan Liu, Zhuang Xu +7

We use inelastic neutron scattering to study spin excitation anisotropy in mechanically detwinned Ba(Fe1-xCox)2As2 with x = 0.048 and 0.054. Both samples exhibit a tetragonal-to-or…

Impact of the first order antiferromagnetic phase transition on the paramagnetic spin excitations and nematic phase of SrFeAs

David W. Tam, Weiyi Wang, Li Zhang +7

Understanding the nature of the electronic nematic phase in iron pnictide superconductors is important for elucidating its impact on high-temperature superconductivity. Here we use…

The Nematic Energy Scale and the Missing Electron Pocket in FeSe

Ming Yi, Heike Pfau, Yan Zhang +12

Superconductivity emerges in proximity to a nematic phase in most iron-based superconductors. It is therefore important to understand the impact of nematicity on the electronic str…

Broken mirror symmetry, incommensurate spin correlations, and nematic order in iron pnictides

Yiming Wang, Wenjun Hu, Rong Yu +1

Motivated by growing indications for a distinct form of nematic correlations in the extremely hole doped iron pnictide compounds FeAs (=K,Rb,Cs), we consider spin-dri…
