Synthesis of thin-long heavy nuclei in ternary collisions
Yoritaka Iwata, Kei Iida, Naoyuki Itagaki
We illustrate the formation of a thin-long structure of heavy nuclei by three-nucleus simultaneous collisions within time-dependent density functional theory. The impact parameter…
Interplay between Spin Polarization and Color Superconductivity in High Density Quark Matter
Y. Tsue, J. da Providencia, C. Providencia +2
Here, it is suggested that a four-point interaction of the tensor type may lead to spin polarization in quark matter at high density. It is found that the two-flavor superconductin…
Time-Dependent Hartree-Fock Approach to Nuclear Pasta at Finite Temperature
Bastian Schuetrumpf, Michael Andreas Klatt, Kei Iida +3
We present simulations of neutron-rich matter at subnuclear densities, like supernova matter, with the time-dependent Hartree-Fock approximation at temperatures of several MeV. The…
Existence of exotic torus configuration in high-spin excited states of Ca
T. Ichikawa, J. A. Maruhn, N. Itagaki +3
We investigate the possibility of the existence of the exotic torus configuration in the high-spin excited states of Ca. We here consider the spin alignments about the symme…
A Role of the Quasiparticle in the Conservation of the Fermion Number
Y. Tsue, C. Providencia, J. da Providencia +1
The role of the "quasiparticle" introduced in last paper by the present authors is discussed. It serves as a guide for the deformation of the Cooper-pair in the BCS-Bogoliubov appr…
The BCS-Bogoliubov and the su(2)-Algebraic Approach to the Pairing Model in Many-Fermion System
Y. Tsue, C. Providencia, J. da Providencia +1
The relation between two approaches to the su(2)-algebraic many-fermion model is discussed: (1) the BCS-Bogoliubov approach in terms of the use of the quasiparticles representing a…
