Optical conductivity of d-wave superconductors
– We study theoretically the optical conductivity of d-wave superconductors like in high temperature cuprates in the presence of impurities. We limit ourselves at T = 0K and focus on the frequency dependence of both σ1(ω) and ωσ2(ω) for ω . 2∆. When the impurity scattering is in the unitary limit, we find a peak in σ1(ω) with ω/∆ ≃ 0.1 ∼ 0.5, which may account for the peak seen by Basov et al. ...
متن کاملOptical conductivity of iron-based superconductors.
The new family of unconventional iron-based superconductors discovered in 2006 immediately relieved their copper-based high-temperature predecessors as the most actively studied superconducting compounds in the world. The experimental and theoretical effort made in order to unravel the mechanism of superconductivity in these materials has been overwhelming. Although our understanding of their m...
متن کاملGreybody factors at large imaginary frequencies
Extending a computation which appeared recently in [1], we compute the transmission and reflection coefficients for massless uncharged scalars and gravitational waves scattered by d ≥ 4 Schwarzschild or d = 4 Reissner-Nordstrøm black holes, in the limit of large imaginary frequencies. The transmission coefficient has an interpretation as the “greybody factor” which determines the spectrum of Ha...
متن کاملOptical conductivity and Raman scattering of iron superconductors
We discuss how to analyze the optical conductivity and Raman spectra of multiorbital systems using the velocity and the Raman vertices in a similar way Raman vertices were used to disentangle nodal and antinodal regions in cuprates. We apply this method to iron superconductors in the magnetic and nonmagnetic states, studied at the mean-field level. We find that the anisotropy in the optical con...
متن کاملAttenuation and velocity dispersion at seismic frequencies
Attenuation and velocity dispersion are strongly dependent on pore fluids, particularly partial gas saturation, and thus could become valuable direct hydrocarbon indicators. Unfortunately, application of these properties is not frequent due to incomplete understanding of the phenomena and lack of appropriate tools to extract the information. Laboratory measurements at frequencies and amplitudes...
