标题： Classical Correlations and Quantum Interference in Ballistic Conductors

摘要： 我们说明经典混沌动力学如何影响介观尺度下的量子特性。 作为模型案例，我们在超越所谓的对角近似的情况下，通过朗道尔形式在半经典条件下研究弹道介观系统中的相干输运，即通过引入经典作用量相关性。 在此背景下，我们回顾并解释了两种用于计算量子修正的基于轨迹的方法：配置空间方法和相空间方法，后者可以被视为不如前者直观但更为普遍。 显示英文摘要

摘要： We illustrate how classical chaotic dynamics influences the quantum properties at mesoscopic scales. As a model case we study semiclassically coherent transport through ballistic mesoscopic systems within the Landauer formalism beyond the so-called diagonal approximation, i.e. by incorporating classical action correlations. In this context we review and explain the two main trajectory-based methods developed for calculating quantum corrections: the configuration space approach and the phase space approach that can be regarded as less illustrative but more general than the first one.
