高度简并混沌辐射光子统计的操纵
Manipulation of photon statistics of highly degenerate chaotic radiation
摘要:
高度简并的混沌辐射具有高斯密度矩阵和大量的模式占据数$f $。如果通过弱透射势垒,其计数统计接近泊松分布。我们表明,第二个相同的障碍,在第一个系列,大大修改了统计。光计数的方差以系数$f$乘以数值系数的方式增加到高于平均值。光计数分布达到一个限制的形式与高斯体和高度不对称的尾巴。这些是弱透射和多重散射结合的一般结果。
英文摘要:
Highly degenerate chaotic radiation has a Gaussian density matrix and a large occupation number of modes $f $. If it is passed through a weakly transmitting barrier, its counting statistics is close to Poissonian. We show that a second identical barrier, in series with the first, drastically modifies the statistics. The variance of the photocount is increased above the mean by a factor $f$ times a numerical coefficient. The photocount distribution reaches a limiting form with a Gaussian body and highly asymmetric tails. These are general consequences of the combination of weak transmission and multiple scattering.
