  • Finite-cluster typical medium theory for disordered electronic systems 
    Ekuma, C. E.; Moore, C.; Terletska, H.; Tam, K. -M.; Moreno, J.; Jarrell, M.; Vidhyadhiraja, N. S. (American Physical Society, 2015)
    We use the recently developed typical medium dynamical cluster (TMDCA) approach [Ekuma et al., Phys. Rev. B 89, 081107 (2014)] to perform a detailed study of the Anderson localization transition in three dimensions for the ...
  • Metal-insulator transition in a weakly interacting disordered electron system 
    Ekuma, C. E.; Yang, S. -X.; Terletska, H.; Tam, K. -M.; Vidhyadhiraja, N. S.; Moreno, J.; Jarrell, M. (American Physical Society, 2015)
    The interplay of interactions and disorder is studied using the Anderson-Hubbard model within the typical medium dynamical cluster approximation. Treating the interacting, nonlocal cluster self-energy [Sigma(c)[(g) over ...
