We propose a general framework that unifies the description of counting statistics of transmitted (fermionic) charges as it is commonly used in the quantum transport community with the description of counting statistics of phonons (bosons). As a particular example, we study on the same footing the counting statistics of electrons transferred through a molecular junction and the corresponding population dynamics of the associated molecular vibrational mode. In the tunnel limit, non-perturbative results in the electron-phonon interaction are derived that unify complementary approaches based on rate equations or on the use of non-equilibrium Green functions.
我们提出了一个通用框架，将量子输运领域中常用的传输（费米子）电荷计数统计的描述与声子（玻色子）计数统计的描述统一起来。作为一个特定的例子，我们以相同的方式研究通过分子结传输的电子的计数统计和相关分子振动模式的相应种群动力学。在隧道极限下，从电子-声子相互作用中推导出非微扰结果，这些结果统一了基于速率方程或使用非平衡格林函数的互补方法。
