Interaction-Induced Adiabatic Cooling for Antiferromagnetism in Optical Lattices
A. -M. Daré, L. Raymond, G. Albinet +1
In the experimental context of cold-fermion optical lattices, we discuss the possibilities to approach the pseudogap or ordered phases by manipulating the scattering length or the…
Crystal field theory of Co in doped ZnO
R. O. Kuzian, A. M. Daré, P. Sati +1
We present a crystal field theory of transition metal impurities in semiconductors in a trigonally distorted tetrahedral coordination. We develop a perturbative scheme to treat cov…
Effect of Hund's exchange on the spectral function of a triply orbital degenerate correlated metal
P. Lombardo, A. - M. Daré, R. Hayn
We present an approach based on the dynamical mean field theory which is able to give the excitation spectrum of a triply degenerate Hubbard model with a Hund's exchange invariant…
Planar spin exchange in LiNiO_2
A. -M Daré, R. Hayn
We study the planar spin exchange couplings in LiNiO2 using a perturbative approach. We show that the inclusion of the trigonal crystal field splitting at the Oxygen sites leads to…
