Simulation of dynamical (u,d,s,c) domain-wall/overlap quarks at the physical point

Ting-Wai Chiu 2019 PoS LATTICE2018 (2019) 040

We perform hybrid Monte-Carlo simulation of $N f = 2 + 1 + 1$ lattice QCD with domain-wall quarks at the physical point. The simulation is carried out on the $L^3 \times T = 64^3 \times 64$ lattice with lattice spacing fm ( fm, and $M_pi L > 3$ ), using the Nvidia DGX-1 (8 V100 GPUs interconnected by the NVLink). To attain the maximal chiral symmetry for a finite extent ( $N s = 16$ ) in the fifth dimension, we use the optimal domain-wall fermion for the quark action, together with the exact one-flavor action for domain-wall fermion. We outline the salient features of our simulation (without topology freezing, and small residual mass), together with the preliminary result of the masses of pi, $K\pm",$ and $D\pm$
