Influence of Pressure on the Structure and Electronic Properties of the Layered Superconductor Y2C2I2
Kyungsoo Ahn, Reinhard K. Kremer, Arndt Simon +3
The structural properties under hydrostatic pressure up to 3 GPa of the layered rare earth carbide halide superconductor Y2C2I2 are studied by neutron powder diffraction at room te…
Band filling and interband scattering effects in MgB: C vs Al doping
Jens Kortus, Oleg V. Dolgov, Reinhard K. Kremer +1
We argue, based on band structure calculations and Eliashberg theory, that the observed decrease of of Al and C doped MgB samples can be understood mainly in terms of a b…
Three-dimensional MgB-type superconductivity in hole-doped diamond
Lilia Boeri, Jens Kortus, O. K. Andersen
We substantiate by calculations that the recently discovered superconductivity below 4 K in 3% boron-doped diamond is caused by electron-phonon coupling of the same type as in MgB$…
Resonant magnetic excitations at high energy in superconducting
S. Pailhes, Y. Sidis, P. Bourges +5
A detailed inelastic neutron scattering study of the high temperature superconductor provides evidence of new resonant magnetic features, in addition to the…
BCS pairing in Fermi systems with several flavors
Carsten Honerkamp, Walter Hofstetter
Motivated by the prospect of Bardeen-Cooper-Schrieffer (BCS) pairing in cold fermionic gases we analyze the superfluid phase of 3 fermionic flavors in the attractive Hubbard model.…
Manifestation of the magnetic resonance mode in the nodal quasiparticle lifetime in superconducting cuprates
A. A. Kordyuk, S. V. Borisenko, A. Koitzsch +9
Studying the nodal quasiparticles in superconducting cuprates by photoemission with highly improved momentum resolution, we show that a new "kink" feature in the scattering rate is…
