A Microscopic View on the Mott transition in Chromium-doped V2O3
S. Lupi, L. Baldassarre, B. Mansart +18
V2O3 is the prototype system for the Mott transition, one of the most fundamental phenomena of electronic correlation. Temperature, doping or pressure induce a metal to insulator t…
Unveiling the hybridization gap in Ce2RhIn8 heavy fermion compound
C. Adriano, F. Rodolakis, P. F. S. Rosa +4
A Kondo lattice of strongly interacting f-electrons immersed in a sea of conduction electrons remains one of the unsolved problems in condensed matter physics. The problem concerns…
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…
Fermi surface collapse and energy scales in Ce2RhIn8
F. Rodolakis, C. Adriano, F. Restrepo +3
In some metals containing a sub-lattice of rare earth or actinide ions, free local spins at high temperatures dissolve into the sea of quantum conduction electrons at low tempe…
Resonant soft x-ray scattering from stripe-ordered LaBaCuO detected by a transition edge sensor array detector
Y. I. Joe, Y. Fang, S. Lee +11
Resonant soft x-ray scattering (RSXS) is a leading probe of valence band order in materials best known for detecting charge density wave order in the copper-oxide superconductors.…
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…
Inequivalent routes across the Mott transition in V2O3 explored by X-ray absorption
F. Rodolakis, P. Hansmann, J. -P. Rueff +14
The changes in the electronic structure of V2O3 across the metal-insulator transition induced by temperature, doping and pressure are identified using high resolution x-ray absorpt…
