论文摘要
在与两个，三个和四个末端连接的Aharonov-Bohm环中系统地研究了受外部磁场系统的线性和非线性传输性能的微可逆性的后果。在独立的电子近似中，完全指定非平衡电流的统计数据的累积生成函数以这些电路的散射矩阵表示。分析研究到电流和第四个累积剂的第三个响应的时间反转对称关系，并根据磁通量的函数进行了分析研究并数值测试。因此，这种关系的有效性在这类开放量子系统中牢固确认。
The consequences of microreversibility for the linear and nonlinear transport properties of systems subjected to external magnetic fields are systematically investigated in Aharonov-Bohm rings connected to two, three, and four terminals. Within the independent electron approximation, the cumulant generating function, which fully specifies the statistics of the nonequilibrium currents, is expressed in terms of the scattering matrix of these circuits. The time-reversal symmetry relations up to the third responses of the currents and the fourth cumulants are analytically investigated and numerically tested as a function of the magnetic flux. The validity of such relations is thus firmly confirmed in this class of open quantum systems.
