论文摘要
分析了四重奏相干状态ANSATZ对质子中子配对的形式含义。在四重奏情况下，计算其概括BCS线性准颗粒算子的非线性歼灭算子。发现它们的结构在许多身体相关函数之间产生非平凡的关系。四重奏相干状态的固有结构已详细介绍，因为它暗示了四重奏图片与对称对称性的对应关系，而对称性恢复的对质子 - 中子配对相关性的凝结式凝结图。
The formal implications of a quartet coherent state ansatz for proton-neutron pairing are analyzed. Its nonlinear annihilation operators, which generalize the BCS linear quasiparticle operators, are computed in the quartetting case. Their structure is found to generate nontrivial relationships between the many body correlation functions. The intrinsic structure of the quartet coherent state is detailed, as it hints to the precise correspondence between the quartetting picture and the symmetry restored pair condensate picture for the proton-neutron pairing correlations.
