激发k玻色子q相干态的高阶反聚束效应

The Higher Order Antibunching Effect of the Excited k-Boson q-Coherent States

用数值计算的方法研究了激发k玻色子q相干态aq+m|z,k,j〉q(k≥3)的3阶反聚束效应.结果表明,3阶反聚束效应受到m(m为增加光子数目)的调节:在主区域内(即小|z|2区内),当j=0时,激发态(m≠0)存在着强烈的3阶反聚束效应,而未激发的态(m=0)不存在3阶反聚束效应;当j≠0时,增加光子(激发)不利于3阶反聚束效应.

The 3rd order antibunching effect of the excited k-boson q-coherent states a^＋mq｜z,k,j〉q（k≥3） is numerically studied. It is shown that the 3rd order antibunching effect is evidently dependent on m. For small x （namely, in the main region）, when j=0, the excited states （m≠0） exhibit strong 3rd order antibunching effect but the unexcited states （m≠0） cannot exhibit 3rd order antibunching effect; when j≠ 0, adding photon （excitation） makes against the 3rd order antibunching effect.
