矩阵几何与相干态

Matrix Geometry and Coherent States

Goro Ishiki

摘要:

提出了一种求矩阵几何经典极限的新方法。我们定义了由D个厄米矩阵X_μ(μ= 1,2,.)的大N序列描述的一般矩阵几何的相干态,D)并构造一个相应的经典空间作为所有相干态的集合。我们还用矩阵元表示了经典空间上的各种几何对象,如度量、Levi-Civita联络、曲率和Poisson张量。该方法在矩阵模型中提供了一类新的可观测量,它们表征了矩阵组态的几何性质。

英文摘要:

We propose a novel method of finding the classical limit of the matrix geometry. We define coherent states for a general matrix geometry described by a large-N sequence of D Hermitian matrices X_μ(μ=1,2, ..., D) and construct a corresponding classical space as a set of all coherent states. We also express various geometric objects on the classical space such as the metric, Levi-Civita connection, curvature and Poisson tensor, in terms of the matrix elements. This method provides a new class of observables in matrix models, which characterize geometric properties of matrix configurations.
