Variational-Iterative Solution of Ground State for Central Potential
The newly developed iterative method based on Green function defined by
quadratures along a single trajectory is combined with the variational method
to solve the ground state quantum wave function for central potentials. As an
example, the method is applied to discuss the ground state solution of Yukawa
potential, using Hulthen solution as the trial function.Comment: 9 pages with 1 tabl
Impact of pairing correlations on the orientation of the nuclear
For the first time, the tilted axis cranking covariant density functional
theory with pairing correlations has been formulated and implemented in a fully
self-consistent and microscopic way to investigate the evolution of the spin
axis and the pairing effects in rotating triaxial nuclei. The measured energy
spectrum and transition probabilities for the Nd-135 yrast band are reproduced
well without any ad hoc renormalization factors when pairing effects are taken
into account. A transition from collective to chiral rotation has been
demonstrated. It is found that pairing correlations introduce additional
admixtures in the single-particle orbitals, and, thus, influence the structure
of tilted axis rotating nuclei by reducing the magnitude of the proton and
neutron angular momenta while merging their direction.Comment: 13 pages, 5 figure
