iTHEMS-RCNP Workshop
Third Workshop on Density Functional Theory: Fundamentals, Developments, and Applications
(DFT2025)

25–27 March 2025
Auditorium, Integrated Innovation Building (IIB), RIKEN Kobe Campus

About This Workshop

The density functional theory (DFT) is one of the powerful methods to solve quantum many-body problems, which, in principle, gives the exact energy and density of the ground state. The accuracy of DFT is, in practice, determined by the accuracy of an energy density functional (EDF) since the exact EDF is still unknown. Currently, DFT has been used in many communities, including nuclear physics, quantum chemistry, and condensed matter physics, while the fundamental study of DFT, such as the first principle derivations of an accurate EDF and methods to calculate many observables from obtained densities and excited states, is still ongoing. However, there has been little opportunity to have interdisciplinary communication.

On December 2022, we had the first workshop on this series (DFT2022) at Yukawa Institute for Theoretical Physics, Kyoto University, and several interdisciplinary discussions and collaborations were started. On February 2024, we had the second workshop on this series (DFT2024) at RIKEN Kobe Campus, and more stimulated discussion occured. To keep and extend collaborations, we organize the third workshop. Since the third workshop, we extend the scope of the workshop to the development and application of DFT as well. In this workshop, the current status and issues of each discipline will be shared towards solving these problems by meeting together among researchers in mathematics, nuclear physics, quantum chemistry, and condensed matter physics.

This workshop mainly comprises lectures/seminars on cutting-edge topics and discussion, while sessions composed of contributed talks are also planned.

This workshop is partially supported by RIKEN iTHEMS Program and Research Center for Nuclear Physics (RCNP), Osaka University.

Instruction for Participants

  • The workshop will be given in English.
  • No registration fee is needed.
  • The workshop will consist of invited seminars and contributed talk sessions. Depending on the number of application, your contribution may be assigned into a poster session.
  • The workshop will be broadcasted via the Zoom conference system. However, the online broadcast is given as the best effort and in-person participation is strongly recommended.
  • We do not accept any online presentation. Thus, all the spearkers are required to attend in person.
  • We plan to have banquet on the evening of 26 March 2025. Those who attend only the banquet are also welcome.
  • We will support financially students and early-career researchers to encourage their participation. Those who want to be supported financially are supposed to register by 31 January 2025. We may not be able to meet your request since the budget is limited.
  • We do not provide any accomodation. Participants are supposed to manage their accomodation by themselves.
  • We do not support any document for a visa application. Information on the visa exemption program can be found MOFA, Japan.
