Direct observation of local K variation and its correlation to electronic inhomogeneity in (Ba1-xKx)Fe2As2 Pnictide
W. K. Yeoh, B. Gault, X. Y. Cui +9
Local fluctuations in the distribution of dopant atoms are a suspected cause of nanoscale electronic disorder or phase separation observed within the pnictide superconductors. Atom…
Topologically protected flat zero-energy surface bands in non-centrosymmetric superconductors
P. M. R. Brydon, Andreas P. Schnyder, Carsten Timm
Nodal non-centrosymmetric superconductors (NCS) have recently been shown to be topologically non-trivial. An important consequence is the existence of topologically protected flat…
Extended Drude model and role of interband transitions in the mid-infrared spectra of pnictides
L. Benfatto, E. Cappelluti, L. Ortenzi +1
We analyze the outcomes of an extended-Drude-model approach to the optical spectra of pnictides, where the multiband nature of the electronic excitations requires a careful analysi…
Vibrational spectrum and electron-phonon coupling of doped solid picene from first principles
Alaska Subedi, Lilia Boeri
We study superconductivity in doped solid picene (C22H14) with linear response calculations of the phonon spectrum and electron-phonon (ep) interaction. We show that the coupling o…
Competing Pairing Symmetries in a Generalized Two-Orbital Model for the Pnictides
Andrew Nicholson, Weihao Ge, Xiaotian Zhang +6
We introduce and study an extended "t-U-J" two-orbital model for the pnictides that includes Heisenberg terms deduced from the strong coupling expansion. Including these J terms ex…
Evidence for competing magnetic instabilities in underdoped
V. Baledent, D. Haug, Y. Sidis +3
We report a polarized neutron scattering study of the orbital-like magnetic order in strongly underdoped and . T…
