Abstract
The topological susceptibility is one of the quantities that has a large discretization error, and the error can be sensitive to the choice of fermion action. We report on our results from physical point simulations with 2+1 flavor Möbius domain wall fermion at finite temperature. We also
present the chiral condensate and disconnected susceptibility. The temporal lattice size is Nt=12
and 16, and the temperature range is around 140 MeV to 250 MeV for the chiral condensate and susceptibility. A coarse lattice with Nt=10 covers up to 500 MeV to measure the topological susceptibility.
