随机矩阵模型谱形状因子中的本征值瞬子

Eigenvalue instantons in the spectral form factor of random matrix model

Kazumi Okuyama

摘要:

研究了高斯酉包络(GUE)随机矩阵模型中谱形状因子的后期平台行为。谱形状因子在平台区的时间导数不是严格为零,而是由于$1/N$展开中的非微扰校正而非零。我们认为这种非微扰修正来自随机矩阵模型的本征值瞬时,并且我们显式计算了作为时间函数的瞬时修正。

英文摘要:

We study the late time plateau behavior of the spectral form factor in the Gaussian Unitary Ensemble (GUE) random matrix model. The time derivative of the spectral form factor in the plateau regime is not strictly zero, but non-zero due to a non-perturbative correction in the $1/N$ expansion. We argue that such a non-perturbative correction comes from the eigenvalue instanton of random matrix model and we explicitly compute the instanton correction as a function of time.
