Nonzero temperature and density
We study QCD with 2+1 flavors at nonzero temperature and nonzero chemical
potential. We present preliminary results obtained from lattice calculations
performed with an improved staggered ferminios action (p4-action) on lattice with temporal
extent N_t = 4 on a line of constant physics with the strange quark mass adjusted to its
physical value and the pion mass of about 220 MeV. We...

Nonzero temperature and density
We investigate the QCD phase diagram based on the strong coupling lattice QCD. In particular, we focus on the interplay between the chiral and deconfinement transitions in the strong coupling framework. We show that the critical temperature at zero chemical potential becomes lower and closer to Mont-Carlo data due to the Polyakov loop effects. We will show some results on finite chemical...

Nonzero temperature and density
Strong Coupling Lattice QCD (SC-LQCD) is a method directly based on QCD,
and has been applied to investigate the properties of the QCD phase diagram
in the finite chemical potential region. The previous studies in next-to-leading
order (NLO) evaluation assert that the effect of NLO in the effective potential
are renormalized in modification of the quark mass and chemical potential in...

Nonzero temperature and density
The Monte-Carlo method is applied to the Polyakov-loop extended Nambu–Jona-Lasinio (PNJL) model. This allows to go beyond the saddle-point approximation in a mean-field calculation and introduces fluctuations around the mean fields. We study the impact of fluctuations on the thermodynamics of the model, in the two quark flavors case. We calculate the second order Taylor expansion coefficients...
