- 論文の詳細を見る
In the coexistent state of the charge (spin) density wave and superconductivity,mixed collective modes are formulated on the basis of a diagram method whichcorresponds to the random phase approximation. This theory gives the basis ofthe collective modes assigned to new Raman peaks in 21-I -NbSe.. Our theorystarts with a more fundamental llamiltonian in which the direct coupling betweentwo modes is not asstumed in contrast with the theory of Ljttlewood and Varma.
