In-gap band in the one-dimensional two-orbital Kanamori-Hubbard model with inter-orbital Coulomb interaction
N. Aucar Boidi, H. Fernández García, Y. Núñez-Fernández +1
We study the electronic spectral properties at zero temperature of the one-dimensional (1D) version of the degenerate two-orbital Kanamori Hubbard model (KHM), one of the well esta…
Asymptotics of the metal-surface Kohn-Sham exact exchange potential revisited
C. M. Horowitz, C. R. Proetto, J. M. Pitarke
The asymptotics of the Kohn-Sham (KS) exact exchange potential of a jelliumlike semi-infinite metal is investigated, in the framework of the optimized-effective-potential…
Anomalous Hall effect in the coplanar antiferromagnetic coloring-triangular lattice
A. C. Duran, S. A. Osorio, M. B. Sturla
We study the anomalous Hall effect on the antiferromagnetic coloring-triangular lattice with a coplanar magnetic configuration in presence of a spin-orbit interaction. The effect o…
Ginzburg-Landau theory for the magnetic and structural transitions in La(CaSr)MnO
L. M. León Hilario, A. A. Aligia
We present a phenomenological theory for the ferromagnetic transition temperature, the magnetic susceptibility at high temperatures, and the structural distortion in the La…
