- 論文の詳細を見る
The low temperature behavior of the quasi-one-dimensional many bipolaronsystem is investigated by the quantum Monte Carlo simulation treating the interchaincoupling by the mean field approximation. In the non-half-filled case, it is found thatthe superconductivity can coexist with the CDW. The coexisting CDW can haveeither the wave length twice the lattice constant or half the fermi wave length. Theformer appears only in the coexistence region with the superconductivity, while thelatter either appears alone or coexists with the superconductivity.
