摘要
证明了库仑耦合的介观结构的相位共振率由电荷松弛电阻决定。电荷松弛电阻与电容共同决定介观结构的 RC 时间常数，在小频率下决定电压波动谱。 presented self-consistent expressions, which give the charge relaxation resistance and consequently the dephasing rate in terms of the diagonal and off-diagonal elements of a generalized Wigner-Smith delay-time matrix. 讨论了平衡态和由量子隧穿噪声产生电荷波动的传输态中的相位共振率。讨论了多种不同的几何结构。该文章将发表于 {\it Quantum Mesoscopic Phenomena and Mesoscopic Devices} 专题。
