Cluster-size dependence in cellular dynamical mean-field theory
Shiro Sakai, Giorgio Sangiovanni, Marcello Civelli +3
We examine the cluster-size dependence of the cellular dynamical mean-field theory (CDMFT) applied to the two-dimensional Hubbard model. Employing the continuous-time quantum Monte…
Signature of antiferromagnetic long-range order in the optical spectrum of strongly correlated electron systems
C. Taranto, G. Sangiovanni, K. Held +3
We show how the onset of a non-Slater antiferromagnetic ordering in a correlated material can be detected by optical spectroscopy. Using dynamical mean-field theory we identify two…
Quantum dynamical screening of the local magnetic moment in Fe-based superconductors
A. Toschi, R. Arita, P. Hansmann +2
We have calculated the local magnetic susceptibility of one of the prototypical Fe-based superconductors (LaFeAsO) by means of the local density approximation + dynamical mean fiel…
Atomic and itinerant effects at the transition metal x-ray absorption K-pre-edge exemplified in the case of VO
P. Hansmann, M. W. Haverkort, A. Toschi +5
X-ray absorption spectroscopy is a well established tool for obtaining information about orbital and spin degrees of freedom in transition metal- and rare earth-compounds. For this…
Evolution of the electronic structure of a Mott system across its phase diagram: an X-ray absorption spectroscopy study of (V(1-x)Crx)2O3
F. Rodolakis, J. -P. Rueff, M. Sikora +12
V2O3 is an archetypal system for the study of correlation induced, Mott-Hubbard metal-insulator transitions. Despite decades of extensive investigations, the accurate description o…
Size control of Charge-Orbital Order in Half-Doped Manganite, LaCaMnO
Hena Das, G. Sangiovanni, A. Valli +2
Motivated by recent experimental results, we study the effect of size reduction on half-doped manganite, LaCaMnO, using the combination of density functional th…
