摘要:

通过随机矩阵理论中的正交多项式方法,研究环形区域上β=2逆温度下的二维Coulomb气体。将Coulomb气体分子间的相关函数表示为行列式形式,并在热力学极限下求其渐近形式。当Coulomb气体系统具有连续旋转对称性时,对应的正交多项式为单项式,可见在薄环形区域极限下相关函数的普适行为。在具有离散旋转对称性的系统中,对应的正交多项式一般不是单项式,观察到普适性的破裂。

英文摘要:

Two-dimensional Coulomb gases on an annulus at a special inverse temperature $β= 2$ are studied by using the orthogonal polynomial method borrowed from the theory of random matrices. The correlation functions among the Coulomb gas molecules are written in determinant forms and their asymptotic forms in the thermodynamic limit are evaluated. When the Coulomb gas system has a continuous rotational symmetry, the corresponding orthogonal polynomials are monomials, and one can see a universal behavior of the correlation functions in a thin annulus limit. In a system with a discrete rotational symmetry, the corresponding orthogonal polynomials are not in general monomials, and a breakdown of the universality is observed.
