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-…
Sine-Gordon description of Beresinskii-Kosterlitz-Thouless physics at finite magnetic field
L. Benfatto, C. Castellani, T. Giamarchi
The Beresinskii-Kosterlitz-Thouless (BKT) physics of vortices in two-dimensional superconductors at finite magnetic field is investigated by means of a field-theoretical approach b…
Field dependence of the magnetic spectrum in anisotropic and Dzyaloshinskii-Moriya antiferromagnets: II. Raman spectroscopy
L. Benfatto, M. B. Silva Neto, A. Gozar +5
We compare the theoretical predictions of the previous article [L. Benfatto and M. B. Silva Neto, cond-mat/0602419], with Raman spectroscopy experiments in Sr(2)CuO(2)Cl(2) and unt…
Field dependence of the magnetic spectrum in anisotropic and Dzyaloshinskii-Moriya antiferromagnets: I. Theory
L. Benfatto, M. B. Silva Neto
We consider theoretically the effects of an applied uniform magnetic field on the magnetic spectrum of anisotropic two-dimensional and Dzyaloshinskii-Moriya layered quantum Heisenb…
One-magnon Raman scattering in La(2)CuO(4): the origin of the field-induced mode
M. B. Silva Neto, L. Benfatto
We investigate the one-magnon Raman scattering in the layered antiferromagnetic La(2)CuO(4) compound. We find that the Raman signal is composed by two one-magnon peaks: one in the…
