Abstract
Superconductivity in the Hubbard model is studied on a series of lattices in which dimers are coupled in various types of arrays. Using fluctuation exchange method and solving the linearized Eliashberg equation, the transition temperature Tc of these systems is estimated to be much higher than that of the Hubbard model on a simple square lattice, which is a model for the high-Tc cuprates. We conclude that these ‘dimer array’ systems can generally exhibit superconductivity with very high Tc. Not only d-electron systems, but also p-electron systems may provide various stages for realizing the present mechanism.
