Real-time Observation of Phonon-Mediated - Interband Scattering in MgB2
Edoardo Baldini, Andreas Mann, Lara Benfatto +11
In systems having an anisotropic electronic structure, such as the layered materials graphite, graphene and cuprates, impulsive light excitation can coherently stimulate specific b…
Coupling of the A_{1g} As-phonon to magnetism in iron pnictides
N. A. García-Martínez, B. Valenzuela, S. Ciuchi +3
Charge, spin and lattice degrees of freedom are strongly entangled in iron superconductors. A neat consequence of this entanglement is the behavior of the A_{1g} As-phonon resonanc…
Nonadiabatic Pauli susceptibility in fullerene compounds
E. Cappelluti, C. Grimaldi, L. Pietronero
Pauli paramagnetic susceptibility is unaffected by the electron-phonon interaction in the Migdal-Eliashberg context. Fullerene compounds however do not fulfill the adiabatic as…
A survey of nonadiabatic superconductivity in cuprates and fullerides
E. Cappelluti, C. Grimaldi, L. Pietronero +1
High- superconductors are characterized by very low carrier densities. This feature leads to two fundamental consequences: on one hand the Fermi energies are correspondingly s…
Interplay of superconductivity with structural phases in a generalized t-J model
R. Zeyher, E. Cappelluti
The phase diagram of the t-J-V model is discussed using a 1/N expansion in terms of X operators. It is shown that a flux phase of d-wave symmetry is stabilized by the Coulomb inter…
Breakdown of Migdal-Eliashberg Theory in RbC
E. Cappelluti, C. Grimaldi, L. Pietronero +2
This paper has been withdrawn. An extended version of this work can be found in E. Cappelluti, C. Grimaldi, L. Pietronero, S. Straessler: Phys. Rev. Lett. 85, 4771 (2000) [cond-mat…
