Infrared nano-imaging of Luttinger liquid plasmons in single walled carbon nanotubes

ORAL

Abstract

Quantum-confined electrons in one dimension (1D) constitute a Luttinger liquid, which features charge spin separation and other intriguing properties distinctly different from the Fermi liquid. Single walled carbon nanotubes (SWNTs) provide the ideal platform to explore such Luttinger liquid physics due to strong lateral quantum confinement and the presence of nanotubes of different species. But a systematic study of how the Luttinger liquid behaviors in carbon nanotubes depend on intrinsic and extrinsic factors such as chirality and doping has been lacking. We performed comprehensive infrared nano-imaging of Luttinger liquid plasmons in carbon nanotubes with different parameters and provide novel insights into Luttinger liquid physics in carbon nanotubes. This in-depth understanding of Luttinger liquid physics in SWNTs is not only of fundamental interests, but also pave the way for various nanophotonic applications based on carbon nanotubes.
