Weak Electron-Phonon Coupling Is Insufficient to Generate Significant CISS in Two-Terminal Transport

Amikam Levy, Vipul Upadhyay

Fully self-consistent calculations find that weak electron-phonon coupling produces negligible spin polarization in two-terminal helical junctions.

Claims

C1strongest claim

In contrast to large polarizations and anomalous size trends reported under approximate treatments, the fully self-consistent calculation yields negligible spin polarization, additionally the electron-phonon coupling mainly renormalizes the spectrum, and transport remains quasi-ballistic across the explored parameter range.

C2weakest assumption

The helical tight-binding model with spin-orbit coupling plus the self-consistent Born approximation for electron-phonon self-energies fully captures the relevant physics without needing additional strong symmetry-breaking terms.

C3one line summary

Fully self-consistent treatment of electron-phonon interactions in helical junctions yields negligible spin polarization, in contrast to results from approximate self-energy schemes.
