The path optimization method is applied to a QCD effective model with a Polyakov loop and
a repulsive vector-type interaction at finite temperature and density to circumvent the model …

In this paper, we give a direct method for calculating the partition function, and hence the

The properties of hadron screening masses around the deconfinement phase transition at
finite baryonic density can be studied by evaluating the Taylor coefficients with respect to the …

We perform two flavor QCD simulations with an imaginary chemical potential and measure

I summarize recent lattice results on QCD at finite temperatures and densities. Studies on
the nature of the QCD transition at the physical point, continuum extrapolations of …

We present the renormalized Taylor expansion of the chiral condensate with chemical
potential. The relation with the Taylor coefficients of meson susceptibilities and the quark …
