A numerical study of a set of random matrices which interpolate Poisson and Gaussian
orthogonal ensembles is reported. The result indicates that the transition from Poisson to …

On the basis of the concept of spontaneous breakdown of the rotation symmetry in the
deformed Hartree-Fock-Bogoliubov minimum as the origin of the nuclear collective rotation …

The present status and future problems in both the classical-level theory and full quantum
theory of nuclear collective dynamics are discussed by putting special emphasis on their …

We formulate a quantum statistical theory for damping of the collective transition embedded
in the highly excited states of nuclei. The theory is formulated on a general basis which …

To visualize complex structure of the excited states in the many-fermion system, a profile
function of the eigenstate within the quantum phase space is defined by using the boson …

In this paper, a recent development of INS-TSUKUBA joint research project on large-
amplitude collective motion is summerized. The classical theory of nuclear collective …

In this paper a simple statistical formalism that takes into account the diabatic motion of a
compound system to calculate total level density is given. The diabatic motion is introduced …

Since the research field of nuclear physics is expanding rapidly, it is becoming more
imperative to develop the microscopic theory of nuclear matter physics which provides us …

The classical-level theory and full quantum theory of nuclear collective dynamics are
discussed. The nonlinear dynamics between the collective and single-particle excitation …

Being based on the dynamical theory of nuclear collective dynamics, in the previous paper,
we have proposed a general method for evaluating the stoehaaticlty of individual …
