| Research Abstract |
To derive the nuclear force from first principle lattice quantum chromo dynamics (QCD) simulations, HAL QCD method was developed and established. The equation of state for asymmetric nuclear matter at finite temperature, which is the key input for describing the supernova explosion, was derived on the basis of the cluster variational method. Also, a reduction formula for the Wilson-fermion determinant necessary to study the phase structure of dense QCD was derived. The Gaussian expansion method for quantum few-body calculation was extended to five-body systems with arbitrary two-body interactions. The Monte Carlo shell model, which is powerful method to study the nuclear Hamiltonian with large dimension, was further developed by improving the numerical argorithm and by introducing a new extrapolation method on the basis of the energy variance. A new code of time-dependent density functional theory with particle paring was developed: It lead to a few orders of magnitude numerical speed-up and was applied to study various nuclear collective motions.
