We propose a new theoretical approach to calculate nuclear structure using bare nuclear interaction, in which the tensor and short-range correlations are described by using the tensor optimized shell model (TOSM) and the unitary correlation operator method (UCOM), respectively. We compare the obtained results using TOSM+UCOM for 4He with the rigorous calculation. We also apply TOSM to the analysis of two-neutron halo nuclei, 6He and 11Li, on the basis of the “core with TOSM”+n+n model. The halo formation of 11Li is explained by inclusion of the tensor correlation in 9Li core, which produces the Pauli-blocking on the p-wave neutrons in 11Li and enhances the s-wave component of halo structure.
