The long-term international workshop on``Mean-field and Cluster Dynamics in Nuclear Systems" (MCD2020) will be held at Yukawa Institute for Theoretical Physics (YITP), Kyoto University, Japan, during 20 April - 29 May 2020. In this workshop, we focus on the low-energy nuclear physics. This workshop is planned as one of the series of long-term workshops sponsored by the Yukawa International Program for Quark-Hadron Sciences (YIPQS).
During 11-15 May, a symposium is held as a series of Yukawa International Seminar (YKIS), which has been one of the main international activities of YITP since 1978. The symposium is held annually, covering essentially all the fields of physics. This year we discuss on the physics of the unstable nuclei, and this period is entitled ``Developments of Physics of Unstable Nuclei (YKIS2020)".
