有限维希尔伯特空间q-畸变谐振子奇相干态非经典特性的数值计算

Numerical Studies on the Nonclassical Properties of Odd Co herent States in a Finite-Dimensional Hilbert Space q-Deformation Harmonic Os cillator

运用数值方法研究了 q - 畸变对有限维Hilbert空间谐振子奇相干态非经典特性的影响 .研究表明 ,q- 畸变使该态出现压缩效应 ,且q- 畸变增大时压缩效应增强 ;但q- 畸变使该态的反聚束效应减弱 ,甚至在一定条件下消失 .

The influences of q deformation on the nonclassi cal properties of odd q-coherent states in a finite-dimensional Hibert spaces ( FDHS ) case are studied by numerical method. It is found that, while q<1, the s queezing effect appears and antibunching effect disappears in some range of r-2. With q deformation increasing, the squeezing degree is stren gthened and the antibunching effect is weakened.
