# Spin-orbit coupling and spectral function of interacting electrons in carbon nanotubes

@article{Schulz2010SpinorbitCA, title={Spin-orbit coupling and spectral function of interacting electrons in carbon nanotubes}, author={Andreas Schulz and Alessandro De Martino and Reinhold Egger}, journal={Physical Review B}, year={2010}, volume={82}, pages={033407} }

The electronic spin-orbit coupling in carbon nanotubes is strongly enhanced by the curvature of the tube surface and has important effects on the single-particle spectrum. Here, we include the full spin-orbit interaction in the formulation of the effective low-energy theory for interacting electrons in metallic single-wall carbon nanotubes and study its consequences. The resulting theory is a four-channel Luttinger liquid, where spin and charge modes are mixed. We show that the analytic…
