复合效应、泡利原理和纠缠

Compositeness effects, Pauli's principle and entanglement

Pedro Sancho

摘要:

我们分析了一些复合效应及其与纠缠的关系。我们表明,一个复合系统的纯度增加,在这个意义上的期望值的偏差运营商,与系统的组件之间的纠缠值大。我们还研究了泡利原理在复合系统中的有效性。它在这里提出的方法的应用范围内是有效的。我们还提出了一个例子,两个相同的费米子,其中一个纠缠与一个可区分的粒子,不相容原理不能应用。这一结果在描述开放系统时可能是重要的。

英文摘要:

We analyse some compositeness effects and their relation with entanglement. We show that the purity of a composite system increases, in the sense of the expectation values of the deviation operators, with large values of the entanglement between the components of the system. We also study the validity of Pauli's principle in composite systems. It is valid within the limits of application of the approach presented here. We also present an example of two identical fermions, one of them entangled with a distinguishable particle, where the exclusion principle cannot be applied. This result can be important in the description of open systems.
