我们发展了一种新的形式主义来处理核多体系统的裸核子-核子相互作用。由于π介子在强相互作用系统中的作用，张量相互作用在核多体系统中起着重要的作用。我们以反对称化分子动力学（AMD）为基本框架，利用张量优化壳模型（TOSM）的概念，在AMD波函数上增加了一个张量相关算子。我们展示了一个系统的和简单的制定利用高斯积分和微分方法和反对称化技术来计算所有的矩阵元素的多体哈密顿量。我们可以自然地包含三体相互作用，并按照张量关联算符的递进顺序系统地计算矩阵元。我们称之为新的形式主义“张量优化反对称化分子动力学”。
We develop a new formalism to treat nuclear many-body systems using bare nucleon-nucleon interaction. It has become evident that the tensor interaction plays important role in nuclear many-body systems due to the role of the pion in strongly interacting system. We take the antisymmetrized molecular dynamics (AMD) as a basic framework and add a tensor correlation operator acting on the AMD wave function using the concept of the tensor-optimized shell model (TOSM). We demonstrate a systematical and straightforward formulation utilizing the Gaussian integration and differentiation method and the antisymmetrization technique to calculate all the matrix elements of the many-body Hamiltonian. We can include the three-body interaction naturally and calculate the matrix elements systematically in the progressive order of the tensor correlation operator. We call the new formalism "tensor-optimized antisymmetrized molecular dynamics".
