Local singlets, frustration, and unconventional superconductivity in the organic charge-transfer solids
arXiv:0809.1583 · doi:10.1016/j.physb.2008.11.079
Abstract
We suggest that superconductivity (SC) in the organic charge transfer solids (CTS) is reached from a Bond-Charge Density Wave (BCDW). We discuss an effective model for the BCDW to SC transition, an attractive U extended Hubbard Hamiltonian with repulsive nearest neighbor interaction V. We discuss experimental consequences of the theory for different classes of CTS superconductors as well as related inorganic materials.
