Unravelling the glue and the competing order in superconducting cuprates
S. Caprara, C. Di Castro, B. Muschler +6
We present Raman scattering experiments in single crystals at various doping levels x and compare the results with theoretical predictions obtained assumi…
Theory of fluctuation conductivity from interband pairing in pnictide superconductors
L. Fanfarillo, L. Benfatto, S. Caprara +2
We derive the effective action for superconducting fluctuations in a four-band model for pnictides, discussing the emergence of a single critical mode out of a dominant interband p…
Multiple Gaps and Superfluid Density from Interband Pairing in Iron Oxypnictides
L. Benfatto, M. Capone, S. Caprara +2
We study a four-band model for the iron oxypnictides, in which the superconducting properties are assumed to be determined by the interband coupling between hole-like and electron-…
On the contribution of nearly-critical spin and charge collective modes to the Raman spectra of high-Tc cuprates
S. Caprara, C. Di Castro, T. Enss +1
We discuss how Raman spectra are affected by nearly-critical spin and charge collective modes, which are coupled to charge carriers near a stripe quantum critical point. We show th…
Low-energy signatures of charge and spin fluctuations in Raman and optical spectra of the cuprates
S. Caprara, C. Di Castro, T. Enss +1
We calculate the optical and Raman response within a phenomenological model of fermion quasiparticles coupled to nearly critical collective modes. We find that, whereas critical sc…
Evidences for pairing of nearly-free quasiparticles from paraconductivity in layered superconducting cuprates
S. Caprara, M. Grilli, B. Leridon +1
We revisit the Aslamazov-Larkin theory of paraconductivity in two dimensions, to distinguish its universal features from the specific features of nearly-free paired fermions. We sh…
