Provides a non-perturbative description of the resonant model

Validates the scattering method as an alternative framework

Abstract

Here we consider a non-perturbative description of the non-interacting resonant model using a scattering approach employed in JCP 152(24) 244126 (2020). We showed that such description coincides with the standard NEGF and Landauer-Buttiker approaches.
