Topological charge changing transitions can induce chirality in the quark-gluon plasma by
the axial anomaly. We study the equilibrium response of the quark-gluon plasma in such a …

We discuss how the simultaneous crossovers of deconfinement and chiral restoration can be
realized. We propose a dynamical mechanism assuming that the effective potential gives a …

The current status of theoretical studies on the quantum chromodynamics (QCD) phase
diagram at finite temperature and baryon chemical potential is reviewed with special emphasis …

We review theoretical approaches to explore the phase diagram of nuclear and quark matter
at high baryon density. We first look over the basic properties of quantum chromodynamics (…

We discuss the fate of chiral symmetry in an extremely strong magnetic field B. We investigate
not only quark fluctuations but also neutral meson effects. The former enhances the chiral-…

We present extensive studies on hot and dense quark matter with two light and one heavy
flavors in the Nambu–Jona-Lasinio model with the Polyakov loop (so-called PNJL model). …

We study the two-flavor Nambu–Jona-Lasinio model with the Polyakov loop in the presence
of a strong magnetic field and a chiral chemical potential μ 5, which mimics the effect of …

We discuss an interpretation that a peak in the sound velocity in neutron star matter, as
suggested by the observational data, signifies strongly coupled conformal matter. The normalized …

Current noninvasive tests for coronary artery disease detect atherosclerosis or regional
ischemia. Global myocardial flow reserve is not routinely identified, although it may be an …

We extensively study the growing behavior of the energy and the pressure components
depending on the space–time rapidity in the framework of the Glasma, which describes the early-…
