Superconductivity in correlated BEDT-TTF molecular conductors: critical temperatures and gap symmetries
Karim Zantout, Michaela Altmeyer, Steffen Backes +1
Starting from an {\it ab initio}-derived two-site dimer Hubbard hamiltonian on a triangular lattice, we calculate the superconducting gap functions and critical temperatures for re…
Role of vertex corrections in the matrix formulation of the random phase approximation for the multiorbital Hubbard model
Michaela Altmeyer, Daniel Guterding, P. J. Hirschfeld +3
In the framework of a multiorbital Hubbard model description of superconductivity, a matrix formulation of the superconducting pairing interaction that has been widely used is desi…
Near-degeneracy of extended and order parameters in quasi-two-dimensional organic superconductors
Daniel Guterding, Michaela Altmeyer, Harald O. Jeschke +1
The symmetry of the superconducting order parameter in quasi-two-dimensional BEDT-TTF organic superconductors is a subject of ongoing debate. We report ab initio density functional…
Evidence for eight node mixed-symmetry superconductivity in a correlated organic metal
Daniel Guterding, Sandra Diehl, Michaela Altmeyer +10
We report a combined theoretical and experimental investigation of the superconducting state in the quasi-two-dimensional organic superconductor -(ET)Cu[N(CN)]Br. Applyi…
