The relation between the symplectic group Sp(4,R) and its Lie algebra: Applications to polymer quantum mechanics

Guillermo Chacón‐Acosta, Angel García-Chung

In this paper, we show the relation between $sp(4,\mathbb{R})$ , the Lie algebra of the symplectic group, and the elements of $Sp(4,\mathbb{R})$ . We use this result to obtain some special cases of symplectic matrices relevant to the study of squeezed states. In this regard, we provide some applications in quantum mechanics and analyze the squeezed polymer states obtained from the polymer representation of the symplectic group. Remarkably, the polymer's dispersions are the same as those obtained for the squeezed states in the usual representation.In this paper, we show the relation between $sp(4,\mathbb{R})$, the Lie algebra of the symplectic group, and the elements of $Sp(4,\mathbb{R})$.
