 My researches have been in the area of quantum field theory and particle physics. Since 1998, I have been working on the exact chiral symmetry on the lattice. In 2003, I proposed the optimal domain-wall fermion (ODWF) which possesses the mathematically maximal chiral symmetry for any finite extent in the fifth dimension. Since 2009, my research group have been working on the dynamical simulations of lattice QCD with ODWF. Since 2019, we have been using many units of Nvidia DGX-V100/A100/H100 GPU server to simulate Nf=2+1+1 lattice QCD with optimal domain-wall quarks at the physical point, on the 64^4 lattices with three lattice spacings, as well as the finite temperature ensembles with the same spatial volumes, for temperatures 130-1540 MeV. Recent physical results from these studies include the topological susceptibility of finite temperature QCD, the hierarchical restoration of chiral symmetries and the emergence of chiral-spin symmetry in high temperature QCD.
