Johannes Motruk, Andreas Mielke: BoseHubbard model on twodimensional line graphs
J. Phys. A: Math. Gen45,

(2012)
.
AbstractWe construct a basis for the manyparticle ground states of the positive hopping BoseHubbard model on line graphs of finite 2connected planar bipartite graphs at sufficiently low filling factors. The particles in these states are localized on nonintersecting vertexdisjoint cycles of the line graph which correspond to nonintersecting edgedisjoint cycles of the original graph. The construction works up to a critical filling factor at which the cycles are closepacked.
