High energy scales in electronic self-energy imaged by optics
J. Hwang, E. J. Nicol, T. Timusk +2
We use a new technique to directly extract an estimate of the quasiparticle self-energy from the optical conductivity which can be easily related to both theory and angle-resolved…
Evolution of the Spin Susceptibility of High- Superconductors
J. Hwang, T. Timusk, E. SChachinger +1
We demonstrate that a new tool, a model independent numerical Eliashberg inversion of the optical self-energy, based on maximum entropy considerations can be used to extract the ma…
Optical Sum Rule in Finite Bands
J. P. Carbotte, E. Schachinger
In a single finite electronic band the total optical spectral weight or optical sum carries information on the interactions involved between the charge carriers as well as on their…
Anomalous Absorption Line in the Magneto-Optical Response of Graphene
V. P. Gusynin, S. G. Sharapov, J. P. Carbotte
The intensity as well as position in energy of the absorption lines in the infrared conductivity of graphene, both exhibit features that are directly related to the Dirac nature of…
Temperature Dependence of the Conductivity Sum Rule in the Normal State due to Inelastic Scattering
L. Benfatto, J. P. Carbotte, F. Marsiglio
We examine the temperature dependence of the optical sum rule in the normal state due to interactions. To be concrete we adopt a weak coupling approach which uses an electron-boson…
Unusual Microwave Response of Dirac Quasiparticles in Graphene
V. P. Gusynin, S. G. Sharapov, J. P. Carbotte
Recent experiments have proven that the quasiparticles in graphene obey a Dirac equation. Here we show that microwaves are an excellent probe of their unusual dynamics. When the ch…
