Topological Transitions and Fractional Charges Induced by Strain and a Magnetic Field in Carbon Nanotubes
Topological Transitions and Fractional Charges Induced by Strain and a Magnetic Field in Carbon Nanotubes
We show that carbon nanotubes (CNT) can be driven through a topological phase transition using either strain or a magnetic field. This can naturally lead to Jackiw-Rebbi soliton states carrying fractionalized charges, similar to those found in a domain wall in the Su-Schrieffer-Heeger model, in a setup with a spatially …
