Electronic correlation assisted ferroelectric metallic state in LiOsO
I. Lo Vecchio, G. Giovannetti, M. Autore +6
LiOsO has been recently identified as the first unambiguous "ferroelectric metal", experimentally realizing a prediction from 1965 by Anderson and Blount. In this work, we inve…
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…
Spectral weight redistribution in (LaNiO3)n/(LaMnO3)2 superlattices from optical spectroscopy
P. Di Pietro, J. Hoffman, A. Bhattacharya +2
We have studied the optical properties of four (LaNiO)/(LaMnO) superlattices (SL) (=2, 3, 4, 5) on SrTiO substrates. We have measured the reflectivity at tem…
Optical conductivity of V4O7 across its metal-insulator transition
I. Lo Vecchio, M. Autore, F. D'Apuzzo +6
The optical properties of a V4O7 single crystal have been investigated from the high temperature metallic phase down to the low temperature antiferromagnetic insulating one. The te…
Witnessing the formation and relaxation of massive quasi-particles in a strongly correlated electron system
Fabio Novelli, Giulio De Filippis, Vittorio Cataudella +17
The non-equilibrium semiconductors physics is based on the paradigm that different degrees of freedom interact on different timescales. In this context the photo-excitation is ofte…
Infrared evidence of a Slater metal-insulator transition in NaOsO3
Irene Lo Vecchio, Andrea Perucchi, Paola Di Pietro +6
The magnetically driven metal-insulator transition (MIT) was predicted by Slater in the fifties. Here a long-range antiferromagnetic (AF) order can open up a gap at the Brillouin e…
