Research interests

Research Interests

  • Large scale nuclear shell-model diagonalization and computational techniques
  • Nuclear force and the construction of effective force from the underlying nucleon-nucleon interaction
  • Structure of atomic nuclei
  • Alpha and cluster decay properties of heavy nuclei
  • Continuum effects in nuclei

Research projects supported by the Swedish research council (VR)

  • A novel many body approach for unstable nuclei (2013-2016)
  • Highly unstable systems and exotic decays (2010-2011)
  • Theory of loosely bound nuclei (led by Ramon Wyss, 2011-2013, 2014-2017)

Close collaborators

I have the great opportunity to work with many senior theoretians and experimentalists. What maybe even more exciting and challenging is the collaboration with younger researchers including undergraduate students as well as Master and PhD students. The list of my collaborators can be seen from my publications. It would be my great pleasure to mention all of them here but please forgive me for not being able to finish it.

Scientific computing

  • In 2006, Chong finished a shell-model code that can carry out very large-scale diagonalizations of effective shell-model Hamiltonians. The code is written in the modern Fortran 90 format. It works in the proton/neutron space and embeds an angular momentum projection procedure similar to that of the famous OXBASH code. Parallel computing is realized with the help of the MPI paradigm. The code works efficiently on the HP Beowulf cluster of the PKU computer center.
  • In 2008, Chong wrote a coupled-channel code with the help of Professor Liotta during my visit to KTH.
