講演要旨:

Symmetry is one of the most important notions to understand the fundamental lows of nature. Using a finite degree of freedom, which is unavoidable for numerical simulations, leaves many symmetry broken. In the main application of the field theory research team, which is QCD (Quantum Chromo Dynamics), chiral symmetry is the most important one. This symmetry is not only crucial to understand the QCD dynamics and then the history of the universe, but also important to control the systematic error associated with the discretization. Using a chiral symmetric formulation, which is made possible even with the finite degree of freedom, some important, unsolved problems are expected to be solved on Fugaku. It is especially so for the study of the high temperature phase transition of QCD, for which the chiral symmetric analysis has not been done in complete manner. I will explain the current status and the future plan of the team toward such large scale simulation on Fugaku and discuss what it would bring to us.
