Finite Cluster Typical Medium Theory for Disordered Electronic Systems
C. E. Ekuma, C. Moore, H. Terletska +4
We use the recently developed typical medium dynamical cluster (TMDCA) approach~[Ekuma \etal,~\textit{Phys. Rev. B \textbf{89}, 081107 (2014)}] to perform a detailed study of the A…
Metal-Insulator-Transition in a Weakly interacting Disordered Electron System
C. E. Ekuma, S. -X. Yang, H. Terletska +4
The interplay of interactions and disorder is studied using the Anderson-Hubbard model within the typical medium dynamical cluster approximation. Treating the interacting, non-loca…
Competing magnetic states, disorder, and the magnetic character of Fe3Ga4
J. H. Mendez, C. E. Ekuma, Y. Wu +11
The physical properties of metamagnetic FeGa single crystals are investigated to explore the sensitivity of the magnetic states to temperature, magnetic field, and sample h…
Study of off-diagonal disorder using the typical medium dynamical cluster approximation
H. Terletska, C. E. Ekuma, C. Moore +3
We generalize the typical medium dynamical cluster approximation (TMDCA) and the local Blackman, Esterling, and Berk (BEB) method for systems with off-diagonal disorder. Using our…
Re-examining the electronic structure of germanium: A first-principle study
C. E. Ekuma, M. Jarrell, J. Moreno +2
We report results from an efficient, robust, ab-initio method for self-consistent calculations of electronic and structural properties of Ge. Our non-relativistic calculations empl…
Electronic, structural, and elastic properties of metal nitrides XN (X = Sc, Y): A first principle study
C. E. Ekuma, D. Bagayoko, M. Jarrell +1
We utilized a simple, robust, first principle method, based on basis set optimization with the BZW-EF method, to study the electronic and related properties of transition metal mon…
