Pressure and alloying effects on the metal to insulator transition in NiS{2-x}Se{x} studied by infrared spectroscopy
A. Perucchi, C. Marini, M. Valentini +11
The metal to insulator transition in the charge transfer NiS{2-x}Se{x} compound has been investigated through infrared reflectivity. Measurements performed by applying pressure to…
Photoemission kinks and phonons in cuprates
D. Reznik, G. Sangiovanni, O. Gunnarssonii +1
One of the possible mechanisms of high Tc superconductivity is Cooper pairing with the help of bosons, which change the slope of the electronic dispersion as observed by photoemiss…
Sum-rules and bath-parametrization for quantum cluster theories
Erik Koch, Giorgio Sangiovanni, Olle Gunnarsson
We analyze cellular dynamical mean-field theory (CDMFT) and the dynamical cluster approximation (DCA). We derive exact sum-rules for the hybridization functions and give examples f…
