Even- and Odd-Displaced Squeezed States
Hong-Yi Fan, Zhongxi Zhang · Communications in Theoretical Physics · 1994
We propose and study a new kind of superposition states: even- and odd-displaced squeezed states, defined as and , which are characteristic of possessing even and odd photon numbers respectively. We find that the even-displaced squeezed state may exhibit stronger squeezing than that of the ordinary squeezed state .
