D. B. Gutman, Yuval Gefen, A. D. Mirlin

摘要:

利用非平衡玻色化技术研究了单沟道量子线中相互作用电子的电流涨落。导出了传输电荷全计数统计量的精确表达式。它是由具有含时散射相位的计数算子的Fredholm行列式给出的。该结果具有非相互作用粒子的计数统计的形式,其具有分数电荷,其由LL线和非相互作用引线之间的边界的散射引起。

英文摘要:

Non-equilibrium bosonization technique is used to study current fluctuations of interacting electrons in a single-channel quantum wire representing a Luttinger liquid (LL) conductor. An exact expression for the full counting statistics of the transmitted charge is derived. It is given by Fredholm determinant of the counting operator with a time dependent scattering phase. The result has a form of counting statistics of non-interacting particles with fractional charges, induced by scattering off the boundaries between the LL wire and the non-interacting leads.
