Tittle: Mean-field studies for nuclear fission and fusion

Abstract: Nuclear fission and fusion are fundamental phenomena in nuclear physics, and so far, many studies have been actively carried out. With the developments of effective interaction and computational resources, it has become realistic to approach theses phenomena by the theoretical calculations. We have developed the method based on mean-field theories to describe fission and fusion. In this presentation, we will show the charge polarization of fission products deduced by the constraint Skyrme Hartree-Fock+BCS model represented in the three-dimensional Cartesian coordinates. And the procedure to describe the superheavy element synthesis using the canonical-basis time-dependent Hartree-Fock-Bogoliubov theory is introduced.

セミナー(Seminar) 2019.10.25: Dr Takeru Yokota (KEK)

We have a seminar by Dr Takeru Yokota, KEK, on October 25th, 2019. The seminar is given in English.

  • Lecturer: Dr Takeru YOKOTA (KEK)
  • Title: Functional-renormalization-group aided density functional theory
  • Time/Date: 13:45-, October 25, 2019
  • Place: Meeting Room B, Center for Computational Sciences (1F), University of Tsukuba
  • Abstract: The functional-renormalization-group aided density functional theory (FRG-DFT) is an attempt to microscopically formulate the density functional theory borrowing ideas from the functional renormalization group. This method is expected to become a powerful approach for the fundamental problems of the density functional theory such as the microscopic determination of the energy density functional and the analyses of excited states involving the large-amplitude collective dynamics.
    In this talk, I will introduce the FRG-DFT and present our works, which includes the formulation for continuum homogeneous matters [1], the analysis of the ground and excited states of a one-dimensional fermionic matter [1, 2], and the application to the two-dimensional homogeneous electron gas [3]. I may also discuss our recent works on the application to systems with arbitrary spin polarization and superfluidity.
