论文摘要
我们通过利用Keldysh技术来分析计算开放式1D Kitaev链中能量和粒子传输的累积产生功能。粒子和能量电流的关节分布遵守参数空间不同区域的不同波动关系，这是由于$ u $（1）对称性破坏和能量保护。我们将Kitaev链作为三个末端系统的热电学讨论，并得出最大工作能力的分析表达。明确检查了到第二阶的响应理论，结果与从波动关系得出的关系一致。
We analytically calculate the cumulant generating function of energy and particle transport in an open 1D Kitaev chain by utilizing the Keldysh technique. The joint distribution of particle and energy currents obeys different fluctuation relations in different regions of the parameter space as a result of $U$(1) symmetry breaking and energy conservation. We discuss the thermoelectricity of the Kitaev chain as a three terminal system and derive an analytical expression of the maximum work power. The response theory up to the second order is explicitly checked, and the result is consistent with the relations derived from the fluctuation relation.
