Anderson localization on the Falicov-Kimball model with Coulomb disorder
Rubens D. B. Carvalho, Guilherme M. A. Almeida, Andre M. C. Souza
The role of Coulomb disorder is analysed in the Anderson-Falicov-Kimball model. Phase diagrams of correlated and disordered electron systems are calculated within dynamical mean-fi…
Local electronic properties in nanoscale systems
Andre M. C. Souza, Hans Herrmann
The local electronic structure on nanoscale chains is investigated theoretically. We propose a mechanism to explain the even-odd oscillation of length distribution of atom chains.…
Hölder mean applied to Anderson localization
Andre M. C. Souza, Daniela de O. Maionchi, Hans J. Herrmann
The phase diagram of correlated, disordered electron systems is calculated within dynamical mean-field theory using the Hölder mean local density of states. A critical disorder str…
Correlated electrons systems on the Apollonian network
Andre M. C. Souza, Hans Herrmann
Strongly correlated electrons on an Apollonian network are studied using the Hubbard model. Ground-state and thermodynamic properties, including specific heat, magnetic susceptibil…
