Description
We investigate the issue of possible restoration of the axial U(1)
symmetry at finite temperature, using lattice simulations with the
Mobius domain-wall fermion. In this talk, we focus on the effects of
near-zero Dirac eigenmodes, which play a crucial role for both
SU(2)xSU(2) chiral symmetry restoration and the restoration/breaking
of axial U(1) symmetry.
Performing simulations at two different volumes, two
different quark masses, and reweighting
to other masses and to overlap Dirac operators,
we study its volume, mass, residual mass dependences.
