Unconventional Superconductivity in Layered Organic Superconductors
نویسنده
چکیده
Like the high-Tc copper oxides, organic superconductors are another class of superconductors that cannot be fully explained by the conventional BCS theory, due to the repulsive effective interactions between the charge carriers. Experiments display similarities between these systems and the high-Tc copper oxides in their pairing symmetry and their phase diagram. In this paper, some results from experiments in organics are summarized and a suggested model of this superconductivity induced by strong electron correlation is discussed.

Two decades ago the epoch making discovery of high Tc cuprate superconductivity by Bednorz and Müller shocked the world’s superconductivity community. However, already in 1979 and 1980, the first heavy fermion superconductor CeCu2Si2 and organic superconductor (TMTSF)2PF6 have been discovered respectively. Also we know now that all these superconductors are unconventional and nodal. Further t...
متن کاملMagnetic field-induced superconductivity: A unique interplay between magnetic and superconducting orderings. (March 3, 2004)
The complex interplay between magnetism and superconductivity is a central topic in condensed matter physics due to increasing evidence indicating that unconventional superconductivity (SC) occurs in the vicinity of magnetically ordered states. The experimental observations inspired models proposing "magnetically mediated" SC pairing in the proximity of magnetic quantum-criticality in a variety...

To understand the mechanism of superconductivity in unconventional super onductors is one of the big challenges in the field of superconductivity. Based on the BCS theory, there is a direct relation between the pairing mechanism and the symmetry of the order parameter. Therefore, identification of the structure of the superconducting gap or the order parameter provides key information on the pa...
متن کاملRotational symmetry breaking in the topological superconductor SrxBi2Se3 probed by upper-critical field experiments
Recently it was demonstrated that Sr intercalation provides a new route to induce superconductivity in the topological insulator Bi2Se3. Topological superconductors are predicted to be unconventional with an odd-parity pairing symmetry. An adequate probe to test for unconventional superconductivity is the upper critical field, Bc2. For a standard BCS layered superconductor Bc2 shows an anisotro...
