To find out how quantum bifurcation phenomena manifest themselves in the space of states, various periodic trajectories accompanied with several sets of bifurcated trajectories are studied for a simple quantum model Hamiltonian under a time-dependent

A new mechanism for the backbending phenomenon in ${}^{48}\mathrm{Cr}$ is discussed based on a careful analysis of the yrast band, where no level crossing of the single-particle orbits is expected. A newly developed numerical code for solving the sel

The phenomenon of band termination of the nuclear collective rotation has been originally discussed by Bohr and Mottelson. The scenario is the following: In the high-spin rotational nucleus, the effect of the Coriolis term produces a tendency to alig

A new constraint is proposed which specifies a Hartree-Fock-Bogoliubov (HFB) subspace to describe a collective rotational band in the yrare region. The ground- and S-bands of 164Er are calculated by using the gradient method under this constraint as

The structure of solutions of the constrained Hartree-Fock method is studied within the time-dependent Hartree-Fock formalism. A new method for reaching various stationary Hartree-Fock points, not accessible by the usual adiabatic constrained Hartree

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 expansion theory. When the anharmonic interaction is sufficiently weak

A general theory capable of exploring the microscopic structure of the time-dependent Hartree-Fock (TDHF) manifold is summarized. It is discussed that each stable fixed point in the TDHF-manifold represents a dynamical stable mean-field which is not

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 dynamics formulated within the time-dependent Hartree-Fock theory is recapitulate
