Far-infrared absorption and the metal-to-insulator transition in hole-doped cuprates
S. Lupi, D. Nicoletti, O. Limaj +5
By studying the optical conductivity of BSLCO and YCBCO, we show that the metal-to-insulator transition (MIT) in these hole-doped cuprates is driven by the opening of a small gap a…
Sub-THz electrodynamics of the graphene-like superconductor CaAlSi
S. Lupi, L. Baldassarre, M. Ortolani +7
We report the first optical study of CaAlSi, a superconductor which displays both the crystal structure of MgB2 and the electronic band structure of intercalated graphites. The ref…
Quasiparticle evolution and pseudogap formation in V2O3: An infrared spectroscopy study
L. Baldassarre, A. Perucchi, D. Nicoletti +10
The infrared conductivity of V2O3 is measured in the whole phase diagram. Quasiparticles appear above the Neel temperature TN and eventually disappear further enhancing the tempera…
Electrodynamics near the Metal-to-Insulator Transition in V3O5
L. Baldassarre, A. Perucchi, E. Arcangeletti +5
The electrodynamics near the metal-to-insulator transitions (MIT) induced, in V3O5 single crystals, by both temperature (T) and pressure (P) has been studied by infrared spectrosco…
Low-energy electrodynamics of superconducting diamond
M. Ortolani, S. Lupi, L. Baldassarre +6
Heavily-boron-doped diamond films become superconducting with critical temperatures well above 4 K. Here we first measure the reflectivity of such a film down to 5 cm,…
Infrared Conductivity and Charge Ordering in NaCoO2
S. Lupi, M. Ortolani, L. Baldassarre +3
The infrared conductivity of NaxCoO2 is studied as a function of doping and temperature for x between 0.5 and 1. Charge localization in CoO2 layers shows up through a far-infrared…
