Laguerre Polynomial States and Phase States in k -Photon Sub-Fock Space
Fan Hong-Yi, Fan Yue · Communications in Theoretical Physics · 1997
Using k -photon Brandt–Greenberg operators we introduce the concept of field intensity-dependent squeezing, and construct the minimum uncertainty states for this squeezing, which turns out to be a Laguerre polynomial state in sub-Fock space. The k -photon phase states is also derived, which turns out to be an SU(1,1) generalized coherent state.
