Resonant inelastic x-ray scattering studies of elementary excitations

LJP Ament, M Van Veenendaal, TP Devereaux… - Reviews of Modern …, 2011 - APS
In the past decade, resonant inelastic x-ray scattering (RIXS) has made remarkable progress
as a spectroscopic technique. This is a direct result of the availability of high-brilliance …

Realistic investigations of correlated electron systems with LDA+ DMFT

K Held, IA Nekrasov, G Keller, V Eyert… - … status solidi (b), 2006 - Wiley Online Library
Conventional band structure calculations in the local density approximation (LDA)[1–3] are
highly successful for many materials, but miss important aspects of the physics and …

Mott Insulators in the Strong Spin-Orbit Coupling Limit:<? format?> From Heisenberg to a Quantum Compass and Kitaev Models

G Jackeli, G Khaliullin - Physical review letters, 2009 - APS
We study the magnetic interactions in Mott-Hubbard systems with partially filled t 2 g levels
and with strong spin-orbit coupling. The latter entangles the spin and orbital spaces, and …

Asymmetric magnetic domain-wall motion by the Dzyaloshinskii-Moriya interaction

SG Je, DH Kim, SC Yoo, BC Min, KJ Lee… - Physical Review B …, 2013 - APS
We demonstrate here that ultrathin ferromagnetic Pt/Co/Pt films with perpendicular magnetic
anisotropy exhibit a sizable Dzyaloshinskii-Moriya interaction (DMI) effect. Such a DMI effect …

Electronic structure calculations using dynamical mean field theory

K Held - Advances in physics, 2007 - Taylor & Francis
The calculation of the electronic properties of materials is an important task of solid-state
theory, albeit particularly difficult if electronic correlations are strong, eg, in transition metals …

Mott Transition and Suppression of Orbital Fluctuations in Orthorhombic Perovskites

E Pavarini, S Biermann, A Poteryaev, AI Lichtenstein… - Physical review …, 2004 - APS
Using t 2 g Wannier functions, a low-energy Hamiltonian is derived for orthorhombic 3 d 1
transition-metal oxides. Electronic correlations are treated with a new implementation of …

Orbital order and fluctuations in Mott insulators

G Khaliullin - Progress of Theoretical Physics Supplement, 2005 - academic.oup.com
Basic mechanisms controlling orbital order and orbital fluctuations in transition metal oxides
are discussed. The lattice driven classical orbital picture, eg like in manganites LaMnO 3, is …

[图书][B] Physics of transition metal oxides

S Maekawa, T Tohyama, SE Barnes, S Ishihara… - 2013 - books.google.com
The fact that magnetite (Fe304) was already known in the Greek era as a peculiar mineral is
indicative of the long history of transition metal oxides as useful materials. The discovery of …

Screened hybrid functional applied to 33 transition-metal perovskites LaO ( = Sc–Cu): Influence of the exchange mixing parameter on the structural …

J He, C Franchini - Physical Review B—Condensed Matter and Materials …, 2012 - APS
We assess the performance of the Heyd-Scuseria-Ernzerhof (HSE) screened hybrid density
functional scheme applied to the perovskite family La MO 3 (M= Sc–Cu) and discuss the role …

Pressure-Induced Quenching of the Jahn-Teller Distortion and Insulator-to-Metal Transition in
