Direct observation of electron thermalization and electron-phonon coupling in photoexcited bismuth
J. Faure, J. Mauchain, E. Papalazarou +7
We investigate the ultrafast response of the bismuth (111) surface by means of time resolved photoemission spectroscopy. The direct visualization of the electronic structure allows…
Surface effects on the Mott-Hubbard transition in archetypal VO
G. Lantz, M. Hajlaoui, E. Papalazarou +9
We present an experimental and theoretical study exploring surface effects on the evolution of the metal-insulator transition in the model Mott-Hubbard compound Cr-doped VO…
Optical properties of V2O3 in its whole phase diagram
I. Lo Vecchio, L. Baldassarre, F. D'Apuzzo +7
Vanadium sesquioxide V2O3 is considered a textbook example of Mott-Hubbard physics. In this paper we present an extended optical study of its whole temperature/doping phase diagram…
Mott-Hubbard transition in V2O3 revisited
P. Hansmann, A. Toschi, G. Sangiovanni +4
The isostructural metal-insulator transition in Cr-doped V2O3 is the textbook example of a Mott-Hubbard transition between a paramagnetic metal and a paramagnetic insulator. We rev…
Coherent Phonon Coupling to Individual Bloch States in Photoexcited Bismuth
E. Papalazarou, J. Faure, J. Mauchain +8
We investigate the temporal evolution of the electronic states at the bismuth (111) surface by means of time and angle resolved photoelectron spectroscopy. The binding energy of bu…
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…
Mott transition in Cr-doped V2O3 studied by ultrafast reflectivity: electron correlation effects on the transient response
B. Mansart, D. Boschetto, S. Sauvage +2
The ultrafast response of the prototype Mott-Hubbard system (V1-xCrx)2O3 was systematically studied with fs pump-probe reflectivity, allowing us to clearly identify the effects of…
Ultrafast transient response and electron-phonon coupling in the iron-pnictide superconductor Ba(Fe(1-x)Co(x))2As2
B. Mansart, D. Boschetto, A. Savoia +7
The transient response of Ba(Fe(1-x)Co(x))2As2, x=0.08 was studied by pump-probe optical reflectivity. After ultrafast photoexcitation, hot electrons were found to relax with two d…
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…
Valence band electronic structure of V2O3: identification of V and O bands
E. Papalazarou, Matteo Gatti, M. Marsi +14
We present a comprehensive study of the photon energy dependence of the valence band photoemission yield in the prototype Mott-Hubbard oxide V2O3. The analysis of our experimental…
