Spin-density-wave instability in graphene doped near the van Hove singularity
D. Makogon, R. van Gelderen, R. Roldán +1
We study the instability of the metallic state towards the formation of a new ground state in graphene doped near the van Hove singularity. The system is described by the Hubbard m…

Coupled quantum wires
D. Makogon, N. de Jeu, C. Morais Smith
We study a set of crossed 1D systems, which are coupled with each other via tunnelling at the crossings. We begin with the simplest case with no electron-electron interactions and…
