Abstract

In the paper, the properties of unequal- power Nj-th power H-squeezing in the first kind of asymmetrical multimode superposition state light field|ψI(ab)q with the superposition of macroscopically distinct two quantum states is studied in detail.It is found that if the sum of squeezed power number Nj of the every model is an odd number, under some certain conditions the state |ψI(ab)q can display the effects of unequal- power Nj-th power H-squeezing that changes periodically.
