论文摘要
在本文中，我们显示了$ sp（4，\ mathbb {r}）$，Symplectic组的Lie代数与Symplectic Group $ sp（4，\ Mathbb {r}）$之间的关系。我们使用此关系来提供挤压操作员$ \ widehat {s}（ζ）$的经典类似物。此经典的挤压矩阵与相关矩阵$ {\ bf v}^{（2）} $具有一些相似之处，其挤压量是相关矩阵中的一半。
In this paper we show the relation between $sp(4,\mathbb{R})$, the Lie algebra of the symplectic group, and the elements of the symplectic group $Sp(4,\mathbb{R})$. We use this relation to provide a classical analog of the squeeze operator $\widehat{S}(ζ)$. This classical squeeze matrix shares some similarities with the correlation matrix ${\bf V}^{(2)}$ and its amount of squeezing is half of that in the correlation matrix.
