Amplitude-Nth-power squeezing of PB phase coherent states

摘要

PB Phase Coherent States are very important quantum states in quantum optics. In Order to investigate the amplitude- Nth -power squeezing of PB Phase Coherent States, we introduce the algebraic properties of the PB phase operator and the PB Phase Coherent States which are constructed by PB phase theory. We applied amplitude- Nth -power squeezing theory to define the Amplitude- Nth -Power Squeezing of PB Phase Coherent States and investigate the characteristic of the amplitude- Nth -power squeezing of PB Phase Coherent States. We obtained surprising results, in that the results were different from the other quantum states. As for l Z) ( PB Phase Coherent State) , the results show that when Z is a real number there only exists amplitude- Nth -power squeezing of X componentwhen Z is a complex number, there exists amplitude- Nth -power squeezing of X component and ? componentwhen Z is a pure imaginary number, if A is odd, then there does not exist amplitude-Nth -power squeezing of X component, but there exists amplitude- Nth -power squeezing of X component and if A is even, then there exists amplitude- Nth -power squeezing of X component, but there does not exist amplitude-Nth -power squeezing of Y component.
