Recently, resonance-like signals for 4n system were reported in experiment. By confining finite 3n and 4n systems in external potential, we use tensor-optimized antisymmetrized molecular dynamics and inverse analytical continuation in the coupling constant method to study the possibility of the resonances. Consistent results are obtained, however, evident dependence on external attraction is observed. Besides, we also study the infinite nuclear matter with unitary correlation operator method and high-momentum pairs.
The former is employed to treat the short-range nucleon-nucleon correlation, while the latter is for the tensor correlation. The equations of state for both neutron matter and symmetric nuclear matter are obtained as well as the Hamiltonian components. Calculations by adding hyperons into these systems in the future are also discussed.
