An Investigation of the Multiple Scattering of Waves in Two-Dimensional Random Media
Numerical studies of the ensemble average, or coherent, wave in a two-dimensional random medium have been undertaken for the steady-state and transient cases. The medium consisted of a tensioned mesh with a uniform distribution of point masses attached at the intersection points of the mesh. For …

Electronic structure and energetics of Fe-based superconductors: Effects of chemical and magnetic disorder in (Ba-X)(Fe-Y)2As2
… scattering theory in combination with the coherent-potential approximation (CPA) to handle chemical (alloying) and magnetic (orientational) disorder, all implemented within a self-consistent-field, density functional theory (DFT). For $Tm$ doping, we detail the Fermi-surface evolution and …
