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.

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.
