从量子到经典输运极限的等效电阻

Equivalent Resistance from the Quantum to the Classical Transport Limit

Saheli Sarkar, Damaris Kroeber, Dirk K. Morr

摘要:

通过引入输运等效网络的概念,我们将等效电阻的概念推广到从相干量子到扩散经典输运的整个范围。我们表明,这个新的概念为我们提供了一个平台,简化量子网络的结构,同时保持其全局和局部输运特性,即使在存在电子-声子或电子-电子相互作用的情况下。这使我们能够描述等效量子网络的演化等效经典电阻网络的相互作用强度增加。

英文摘要:

We generalize the concept of equivalent resistance to the entire range from coherent quantum to diffusive classical transport by introducing the notion of transport equivalent networks. We show that this novel concept presents us with a platform to simplify the structure of quantum networks while preserving their global and local transport properties, even in the presence of electron-phonon or electron-electron interactions. This allows us to describe the evolution of equivalent quantum networks to equivalent classical resistor networks with increasing interaction strength.
