Non-rigid band shift and non-monotonic electronic structure changes upon doping in the normal state of the pnictide high temperature superconductor Ba2(Fe1-xCox)2As2
PPaolo Vilmercati, Sung-Kwan Mo, Alexei Fedorov +8
We report systematic Angle Resolved Photoemission (ARPES) experiments using different photon polarizations and experimental geometries and find that the doping evolution of the nor…
Towards a quantitative description of tunneling conductance of superconductors: application to LiFeAs
A. Kreisel, R. Nelson, T. Berlijn +11
Since the discovery of iron-based superconductors, a number of theories have been put forward to explain the qualitative origin of pairing, but there have been few attempts to make…
Impact of Iron-site defects on Superconductivity in LiFeAs
Shun Chi, Ramakrishna Aluru, Udai Raj Singh +10
In conventional s-wave superconductors, only magnetic impurities exhibit impurity bound states, whereas for an s+- order parameter they can occur for both magnetic and non-magnetic…
Generalized Multiband Typical Medium Dynamical Cluster Approximation: Application to (Ga,Mn)N
Yi Zhang, R. Nelson, Elisha Siddiqui +7
We generalize the multiband typical medium dynamical cluster approximation and the formalism introduced by Blackman, Esterling and Berk so that it can deal with localization in mul…
