概要
- 論文の詳細を見る
A new superconducting phase is found in the two-dimensional t-J model near half-filling withinthe mean-field theory and Gutzwiller approximation. This state has a spatial dependence of orderparameters which is interpreted as a mixing of the extended .s-wave component with the finitetotal momentum in addition to the d.'a .,x-wave symmetry. The origin of this peculiar pairingis investigated. There is no node in the gap function in the new state and possible experimentalconseqtnences are discussed.
