Characterization of dipolar current-based metamaterials showing a single resonance in the terahertz spectrum
C. Rizza, E. Palange, P. Carelli +4
We will report on the electromagnetic response due to induced dipolar currents in metamaterials of 2-dimensional array of metallic elements. Used as frequency selectors, the metama…
Substrateless metamaterials at mid-infrared frequencies
F. Mattioli, M. Ortolani, O. Limaj +2
We report on the fabrication and mid-infrared transmission properties of free-standing thin metal films, periodically patterned with holes at periods down to 2 microns and area of…
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…
Two-band parallel conductivity at terahertz frequencies in the superconducting state of MgB.
M. Ortolani, P. Dore, D. Di Castro +7
The optical response of the two-band superconductor MgB has been studied in the 0.7-4 THz range on films with very low impurity level. The effect of the high-energy -gap is…
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…
