Mixed valency and site-preference chemistry for Cerium and its compounds: A predictive DFT study
Aftab Alam, D D Johnson
Cerium and its technologically relevant compounds are examples of anomalous mixed valency, originating from two competing oxidation states -- itinerant Ce and localized Ce$^…

Interplay of force constants in the lattice dynamics of disordered alloys : An ab-initio study
Rajiv K. Chouhan, Aftab Alam, Subhradip Ghosh +1
A reliable prediction of interatomic force constants in disordered alloys is an outstanding problem. This is due to the need for a proper treatment of multisite (atleast pair) corr…

Low-energy, planar magnetic defects in BaFe2As2: nanotwins, twins, antiphase and domain boundaries
S. N. Khan, Aftab Alam, D. D. Johnson
In BaFe2As2, structural and magnetic planar defects begin to proliferate below the structural phase transition, affecting descriptions of magnetism and superconductivity. We study…
