We verify the validity of the Cohen-Gallavotti fluctuation theorem for the strongly correlated problem of charge transfer through an impurity in a chiral Luttinger liquid, which is realizable experimentally as a quantum point contact in a fractional quantum Hall edge state device. This is accomplished via the development of an analytical method to calculate the full counting statistics of the problem in all the parameter regimes involving the temperature, the Hall voltage, and the gate voltage.
我们验证了在手性 Luttinger 液体中通过杂质的电荷转移的强关联问题的 Cohen-Gallavotti 涨落定理的有效性,这在实验上可以实现为分数量子 Hall 边缘态器件中的量子点接触。这是通过开发一种分析方法来实现的,该方法可以计算在涉及温度、霍尔电压和栅极电压的所有参数范围内的问题的全计数统计。
