The role of disorder symmetry in a dirty superconductor: a Bogoliubov-deGennes (BdG) study

Sanjeev Kumar, Prabuddha B. Chakraborty

We study the effect of disorder symmetry in a disordered s-wave superconductor. We begin with an attractive Hubbard model on a two-dimensional square lattice in the presence of dia…

Spin-orbital frustrations and anomalous metallic state in iron-pnictide superconductors

F. Krüger, S. Kumar, J. Zaanen +1

We develop an understanding of the anomalous metal state of the parent compounds of recently discovered iron based superconductors starting from a strong coupling viewpoint, includ…

Mott State and Quantum Critical Points in Rare-Earth Oxypnictides $R O_{1 - x} F_{x} F e A s$ ( $R = L a, S m, N d, P r, C e$ )

Gianluca Giovannetti, Sanjeev Kumar, Jeroen van den Brink

We investigate the magnetic phase diagram of the newly discovered iron-based high temperature oxypnictide superconductors of the type RO $_{1 - x}$ F $_{x}$ FeAs, with rare earths R=La, S…
