Optics clues to pairing glues in high T cuprates
E. van Heumen, A. B. Kuzmenko, D. van der Marel
We analyze optical spectra of high temperature superconductors using a minimal model of electrons coupled to bosons. We consider the marginal Fermi liquid theory and the spin fluct…

Optical determination of the relation between the electron-boson coupling function and the critical temperature in high T cuprates
E. van Heumen, E. Muhlethaler, A. B. Kuzmenko +4
We take advantage of the connection between the free carrier optical conductivity and the glue function in the normal state, to reconstruct from the infrared optical conductivity t…

Optical and thermodynamic properties of the high-temperature superconductor HgBa_2CuO_4+delta
E. van Heumen, R. Lortz, A. B. Kuzmenko +9
In- and out-of-plane optical spectra and specific heat measurements for the single layer cuprate superconductor Hg-1201 at optimal doping (Tc = 97 K) are presented. Both the in-pla…
