复数域中的Landauer电导：找到封闭形式解的途径
Landauer conductance in the complex domain: A path to find closed-form solutions
摘要：
Landauer公式允许我们在理论上描述介观系统中的传输函数的电导。我们提出了一个一般的方法来评估的传输函数在复杂的域连接到半无限原子链的系统。这揭示了复杂的共轭对的简单极点，负责传输峰值在实域评估的存在。这导致我们制定一个封闭形式的表达式的传输函数。
英文摘要：
The Landauer formula allows us to describe theoretically the conductance in terms of the transmission function in a mesoscopic system. We propose a general method to evaluate the transmission function in the complex domain for systems connected to semi-infinite atomic chains. This reveals the presence of complex-conjugated pairs of simple poles that are responsible for transmission peaks in the real-domain evaluations. This leads us to formulate a closed-form expression for the transmission function.
