WebJun 26, 2014 · The non-equilibrium Greenʼs function formalism is mathematically equivalent to the wave function approach due to the Fisher–Lee relation, however it is less stable . Without loss of generality, we can consider the case with a single lead. This is possible because several leads can always be considered as a single effective lead with disjoint ...
