论文摘要
我们研究NAMB-JONA-LASINIO模型框架内的旋转缸内的手性相变。施加光谱边界条件以避免比光快。我们研究了圆柱体的几何形状和旋转如何在有限温度和化学势下影响手性相变。还考虑了由有限的大小和旋转引起的不均匀效应。发现有限的大小将降低手性转变温度并提高手性过渡性化学势，而旋转则降低了手性过渡温度和化学势。此外，我们讨论了结果对重离子碰撞和中子星状态方程的含义。
We study the chiral phase transition inside a rotating cylinder within the framework of the Namb--Jona-Lasinio model. A spectral boundary condition is imposed to avoid faster than light. We investigate how the geometry of the cylinder and rotation influence the chiral phase transition at finite temperature and chemical potential. The inhomogeneous effects caused by the finite size and rotation are also taken into account. It is found that finite size will reduce the chiral transition temperature and raises the chiral transition chemical potential, while the rotation reduces both the chiral transition temperature and chemical potential. In addition, we discuss the implications of our results in heavy-ion collisions and equation of states of neutron star.
