| Research Abstract |
In the physics of the relativistic heavy-ion collision experiments, the chiral phase transition is described including the effects of the pion-pair excitation. Also, it is shown that the disoriented chiral condensates can be realized as a quasi-stable state. As for the quark-hadron phase transition, the phase boundary between hadron phase and the color-superconducting phase is shown by using the quark-Bonn model as a function of the ration of quark-pair and the particle-hole type interaction strength. Further, the shear viscosity of the quantum gluon matter is investigated and it is shown that the value of shear viscosity is small.
