Tensor-optimized antisymmetrized molecular dynamics in nuclear physics

Understand

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.
