中间态的高阶压缩和高阶亚泊松光子统计
Higher Order Squeezing and Higher Order Subpoissonian Photon Statistics in Intermediate States
摘要：
最近，我们提出了Hong-Mandel高阶压缩和高阶亚泊松光子统计的更简单的判据[Phys.Lett. A 374（2010）1009]。本文利用这些简化的判据研究了在不同的中间态，如广义二项式态、超几何态、负二项式态和加光子相干态中观测HOSPS和HOS的可能性。结果表明，这些态可以满足HOS和HOSPS条件。它还表明，非经典的深度和区域可以通过控制各种参数有关的中间状态。此外，我们还分析了高阶非经典性的不同签名之间的相互关系，参考这些中间状态。我们观察到，在不存在HOS的情况下，广义二项式态可以显示出HOSPS的特征。前面我们已经证明了NLVSS在没有HOSPS的情况下显示了HOS。从而证明了同阶的HOSPS和HOS是相互独立的现象。
英文摘要：
Recently simpler criteria for the Hong-Mandel higher order squeezing (HOS) and higher order subpossonian photon statistics (HOSPS) are provided by us [Phys. Lett. A 374 (2010) 1009]. Here we have used these simplified criteria to study the possibilities of observing HOSPS and HOS in different intermediate states, such as generalized binomial state, hypergeometric state, negative binomial state and photon added coherent state. It is shown that these states may satisfy the condition of HOS and HOSPS. It is also shown that the depth and region of nonclassicality can be controlled by controlling various parameters related to intermediate states. Further, we have analyzed the mutual relationship between different signatures of higher order nonclassicality with reference to these intermediate states. We have observed that the generalized binomial state may show signature of HOSPS in absence of HOS. Earlier we have shown that NLVSS shows HOS in absence of HOSPS. Consequently it is established that the HOSPS and HOS of same order are independent phenomenon.
