The study of the dynamical phase transitions and the quark and /or gluon matter in the relativistic heavy ion collisions

在相对论重离子碰撞实验的物理学中，手征相变被描述为包括介子对激发的影响。研究还表明，失定向手性凝聚体可以实现准稳态。对于夸克-强子相变，用夸克-波恩模型描述了强子相和色超导相之间的相界，它是夸克对比和粒子-空穴型相互作用强度的函数。进一步研究了量子胶子物质的剪切粘度，结果表明，量子胶子物质的剪切粘度很小。

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.
