Retardation effects and the Coulomb pseudopotential in the theory of superconductivity
Johannes Bauer, Jong E. Han, Olle Gunnarsson
In the theory of electron-phonon superconductivity both the magnitude of the electron-phonon coupling as well as the Coulomb pseudopotential are important to determine th…
Proximity effect with noncentrosymmetric superconductors
Gaetano Annunziata, Dirk Manske, Jacob Linder
We describe the superconducting proximity effect taking place in a contact between a noncentrosymmetric superconductor and a diffusive normal/ferromagnetic metal within the quasicl…
Electronic band structure and momentum dependence of the superconducting gap in (Ca, Na)Fe2As2 from angle-resolved photoemission spectroscopy
D. V. Evtushinsky, V. B. Zabolotnyy, L. Harnagea +10
Electronic structure of newly synthesized single crystals of calcium iron arsenide doped with sodium with Tc ranging from 33 to 14 K has been determined by angle-resolved photoemis…
Two Ising-like magnetic excitations in a single-layer cuprate superconductor
Yuan Li, G. Yu, M. K. Chan +10
There exists increasing evidence that the phase diagram of the high-transition temperature (Tc) cuprate superconductors is controlled by a quantum critical point. One distinct theo…
Fermi Surface Reconstruction by Dynamic Magnetic Fluctuations and Spin-Charge Separation Near an O(3) Quantum Critical Point
Michael Holt, Jaan Oitmaa, Wei Chen +1
Stimulated by the small/large Fermi surface controversy in the cuprates we consider a small number of holes injected into the bilayer antiferromagnet. The system has an O(3) quantu…
Manifestation of impurity induced s_{+-} -> s_{++} transition: multiband model for dynamical response functions
D. V. Efremov, A. A. Golubov, O. V. Dolgov
We investigate effects of disorder on the density of states, the single particle response function and optical conductivity in multiband superconductors with s_{+-} symmetry of the…
