# Comment on "Electron transport through correlated molecules computed using the time-independent Wigner function: Two critical tests"

## TL;DR

This paper defends the many electron correlated scattering (MECS) approach by analytically demonstrating that it correctly reproduces conductance quantization with open system boundary conditions, countering previous numerical criticisms.

## Contribution

The authors provide an analytical model showing that the MECS approach accurately captures conductance quantization, addressing prior claims of its inadequacy based on numerical methods.

## Key findings

- Analytical model confirms conductance quantization in MECS
- Open boundary conditions are effective in the MECS approach
- Counteracts previous numerical criticisms of MECS

## Abstract

The many electron correlated scattering (MECS) approach to quantum electronic transport was investigated in the linear response regime [I. Baldea and H. Koeppel, Phys. Rev. B. 78, 115315 (2008)]. The authors suggest, based on numerical calculations, that the manner in which the method imposes boundary conditions is unable to reproduce the well-known phenomena of conductance quantization. We introduce an analytical model and demonstrate that conductance quantization is correctly obtained using open system boundary conditions within the MECS approach.
