Tight binding model for iron pnictides
M. J. Calderon, B. Valenzuela, E. Bascones
We propose a five-band tight-binding model for the Fe-As layers of iron pnictides with the hopping amplitudes calculated within the Slater-Koster framework. The band structure foun…

Effect of the tetrahedral distortion on the electronic properties of iron-pnictides
M. J. Calderon, B. Valenzuela, E. Bascones
We study the dependence of the electronic structure of iron pnictides on the angle formed by the arsenic-iron bonds. Within a Slater-Koster tight binding model which captures the c…

Limited local electron-lattice coupling in manganites
D. Sanchez, M. J. Calderon, J. Sanchez-Benitez +4
(Pr,Ca)MnO3 is the archetypal charge-ordered manganite, but in Pr0.48Ca0.52MnO3 we find (using convergent-beam electron diffraction and dark-field images) that the superlattice per…
