Two-dimensional Massless Dirac Fermions in Antiferromagnetic AFe2As2 (A = Ba, Sr)
Zhi-Guo Chen, Luyang Wang, Yu Song +7
We report infrared studies of AFeAs (A = Ba, Sr), two representative parent compounds of iron-arsenide superconductors, at magnetic fields (B) up to 17.5 T. Optical tra…
Observation of an Emergent Coherent State in the Iron-Based Superconductor KFeAs
Run Yang, Zhiping Yin, Yilin Wang +5
The optical properties of KFeAs have been measured for light polarized in the a-b planes over a wide temperature and frequency range. Below K, where this…
A single nodal loop of accidental degeneracies in minimal symmetry: triclinic CaAs
Y. Quan, Z. P. Yin, W. E. Pickett
The existence of closed loops of degeneracies in crystals has been intimately connected to associated crystal symmetries, raising the question: what is the minimum symmetry require…
Uniaxial pressure effect on the magnetic ordered moment and transition temperatures in BaFeAs (Co, Ni)
David W. Tam, Yu Song, Haoran Man +22
We use neutron diffraction and muon spin relaxation to study the effect of in-plane uniaxial pressure on the antiferromagnetic (AF) orthorhombic phase in BaFeAs and its Co-…
Spin excitations and the Fermi surface of superconducting FeS
Haoran Man, Jiangang Guo, Rui Zhang +17
High-temperature superconductivity occurs near antiferromagnetic instabilities and nematic state. Debate remains on the origin of nematic order in FeSe and its relation with superc…
