Phonon Mode Spectroscopy, Electron-Phonon Coupling and the Metal-Insulator Transition in Quasi-One-Dimensional M2Mo6Se6
A. P. Petrović, R. Lortz, G. Santi +9
We present electronic structure calculations, electrical resistivity data and the first specific heat measurements in the normal and superconducting states of quasi-one-dimensional…
Two-gap superconductivity in MgB: clean or dirty?
I. I. Mazin, O. K. Andersen, O. Jepsen +5
A large number of experimental facts and theoretical arguments favor a two-gap model for superconductivity in MgB. However, this model predicts strong suppression of the crit…
Specific heat of MgB in a one- and a two-band model from first-principles calculations
A. A. Golubov, J. Kortus, O. V. Dolgov +6
The heat capacity anomaly at the transition to superconductivity of the layered superconductor MgB is compared to first-principles calculations with the Coulomb repulsion, $μ^\…
Beyond Eliashberg superconductivity in MgB2: anharmonicity, two-phonon scattering, and multiple gaps
Amy Y. Liu, I. I. Mazin, Jens Kortus
Density-functional calculations of the phonon spectrum and electron-phonon coupling in MgB are presented. The phonons, which involve in-plane B displacements, couple s…
Electronic structure of MgB: X-ray emission and absorption studies
E. Z. Kurmaev, I. I. Lyakhovskaya, J. Kortus +8
Measurements of x-ray emission and absorption spectra of the constituents of MgB are presented. The results obtained are in good agreement with calculated x-ray spectra, with d…
