New application of Dirac's representation: N-mode squeezing enhanced operator and squeezed state

Xue-xiang Xu, Li-yun Hu, Hong-yi Fan

It is known that exp[i\lamda(Q_1P_1-i/2)] is a unitary single-mode squeezing operator, where Q_1,P_1 are the coordinate and momentum operators, respectively. In this paper we emplo…
