Journal ArticleDOI
Collapse of magnetic moment drives the Mott transition in MnO
Jan Kuneš,Jan Kuneš,Alexey V. Lukoyanov,V. I. Anisimov,Richard T. Scalettar,Warren E. Pickett +5 more
TL;DR: Results are reported for the classic correlated insulator MnO that reproduce a simultaneous moment collapse, volume collapse and metallization transition near the observed pressure, and identify the mechanism as collapse of the magnetic moment due to an increase of crystal-field splitting, rather than to variation in the bandwidth.
Journal ArticleDOI
Magnetic state and electronic structure of the δ and α phases of metallic Pu and its compounds
TL;DR: In this article, a spin-orbit coupling in the 5f shell was shown to lead to the clear splitting of 5f states into f 5/2 and f 7/2 subbands even in the constrained LDA calculation.
Journal ArticleDOI
NiO: correlated band structure of a charge-transfer insulator.
Jan Kuneš,Jan Kuneš,V. I. Anisimov,Sergey L. Skornyakov,Alexey V. Lukoyanov,Dieter Vollhardt +5 more
TL;DR: The band structure of the prototypical charge-transfer insulator NiO is computed by using a combination of an ab initio band structure method and the dynamical mean-field theory with a quantum Monte-Carlo impurity solver, and the low-energy Zhang-Rice bands with strongly k-dependent orbital character are obtained.
Journal ArticleDOI
Magnetic Moment Collapse-Driven Mott Transition in MnO
TL;DR: In this paper, the Mott transition in correlated electron systems has been investigated and the authors identify the mechanism as collapse of the magnetic moment due to increase of crystal field splitting, rather than to variation in the bandwidth.
Journal ArticleDOI
Local correlations and hole doping in NiO: A dynamical mean-field study
TL;DR: In this paper, a combination of ab initio band-structure methods and dynamical mean-field theory was used to study the single-particle spectrum of the prototypical charge-transfer insulator NiO.
