Jian‐Sheng Wang, TK Liu, Zhan Zhan
Abstract
The eigenstates of the Kth powers (K greater than or equal to3) of the annihilation operator of the Q-deformed non-harmonic oscillator are constructed, and their completeness and higher-order squeezing properties are investigated. The results show that they form a complete Hilbert space, and the Mth order [M = (n + 1/2) K; n = 0,1,2,...] squeezing effects exist in all of the eigenstates when K is even.
