Structure–property correlations in organic and organometallic superconductors

Tunnelling in organic superconductors

We discuss the possibility of deciding on the symmetry of the superconducting phase in the organic superconductors (Bechgaard salts), using tunnelling experiments. We first briefly review the properties of organic superconductors, and the possibility to have unconventional (triplet) superconductivity in these systems. We then present a simple scheme for computing the full current-voltage charac...

Bipolaron density-wave driven by antiferromagnetic correlations and frustration in organic superconductors

We describe the paired electron crystal (PEC) which occurs in the interacting frustrated twodimensional 4filled band. The PEC is a charge-ordered state with nearest-neighbor spin singlets separated by pairs of vacant sites, and can be thought of as a bipolaron density wave. The PEC has been experimentally observed in the insulating state proximate to superconductivity in the organic chargetrans...

Strong correlations in organic charge transfer salts: superconductors, Mott insulators, bad metals and spin liquids

Organic topological insulators in organometallic lattices.

Topological insulators are a recently discovered class of materials having insulating bulk electronic states but conducting boundary states distinguished by nontrivial topology. So far, several generations of topological insulators have been theoretically predicted and experimentally confirmed, all based on inorganic materials. Here, based on first-principles calculations, we predict a family o...
