Interactions in composite graphene-based electronic systems.

We focus on the analytical description of interacting electrons in novel quasi-onedimensional graphene-based systems: partially unzipped nanotubes and quantum spin Hall (QSH) edge states. Unlike their higher-dimensional counterparts, such systems oftendisplay Luttinger-liquid instead of Fermi-liquid behaviour, i.e. the fundamental excitations are not individual quasi-particles, but density waves that each can carry charge or spin.
